Add subnet routing and param.cgi-less settings fallback

- Advertise routes (subnet router) support wired through run scripts and params
- Settings UI tries param.cgi first, then falls back to an app-hosted endpoint
  exposed via manifest reverseProxy, so devices without param.cgi (recorder/NVR
  class) can load and save settings without a reinstall
- Embedded GSocketService HTTP server in param_bridge serves the fallback
- Adds gio-2.0 dependency; correct aarch64 tailscale binaries

-## Proxy Support
+## Settings
 
-All non-ROOT variants expose two local proxy endpoints that route outbound traffic through the Tailscale tunnel:
+All parameters are configurable via the web UI (**Open → Settings** card) and take effect immediately without reinstalling:
 
-### HTTP CONNECT Proxy — `http://127.0.0.1:8080`
+| Parameter | Default | Description |
+|---|---|---|
+| Custom Server URL | *(empty)* | Control server URL for [Headscale](https://headscale.net/) or other self-hosted servers. Leave blank to use Tailscale's official servers. |
+| Auth Key | *(empty)* | Pre-authentication key (`tskey-auth-...`). Cleared automatically after first successful connection. Leave blank to authenticate via browser. |
+| HTTP Proxy Port | `8080` | Port for the outbound HTTP/HTTPS proxy. |
+| SOCKS5 Proxy Port | `1080` | Port for the outbound SOCKS5 proxy. |
+| Accept DNS | `off` | Passes `--accept-dns=true` to `tailscale up`. Allows the tailnet to push DNS settings to the camera. Off by default to avoid overriding the camera's DNS configuration. Not available on `armv7hf_acap3`. |
+| Accept Routes | `off` | Passes `--accept-routes=true` to `tailscale up`. Allows the camera to use subnet routes advertised by other nodes in the tailnet. Not available on `armv7hf_acap3`. |
+
+---
+
+
+All non-ROOT variants expose two local proxy endpoints that route outbound traffic through the Tailscale tunnel. The ports are configurable via **Settings → HTTP Proxy Port / SOCKS5 Proxy Port** in the web UI.
+
+### HTTP CONNECT Proxy — `http://127.0.0.1:8080` (default)
 
 Routes HTTP and HTTPS traffic. Set this wherever an HTTP/HTTPS proxy field is available on the camera:
 
 | Location | Field | Value |

-| System → Network → Global proxies | HTTPS proxy | `http://127.0.0.1:8080` |
-| System → MQTT → Broker | HTTP proxy | `http://127.0.0.1:8080` |
-| System → MQTT → Broker | HTTPS proxy | `http://127.0.0.1:8080` |
+| System → Network → Global proxies | HTTP proxy | `http://127.0.0.1:<port>` |
+| System → Network → Global proxies | HTTPS proxy | `http://127.0.0.1:<port>` |
+| System → MQTT → Broker | HTTP proxy | `http://127.0.0.1:<port>` |
+| System → MQTT → Broker | HTTPS proxy | `http://127.0.0.1:<port>` |
 
-### SOCKS5 Proxy — `127.0.0.1:1055`
+### SOCKS5 Proxy — `127.0.0.1:1080` (default)
 
-For ACAP apps or services that support SOCKS5, set their proxy to `127.0.0.1:1055`.
+For ACAP apps or services that support SOCKS5, set their proxy to `127.0.0.1:<port>`.
 
-> Proxy addresses are shown in the **Connection Details** panel of the web UI when connected.
+> The active proxy addresses are always shown in the **Proxy Configuration** card of the web UI.
+
+> If you change a port that is already in use by another process, the app will log an error and exit rather than silently falling back to a different port.
+

+
+## Accessing Tailnet Services from the Camera
+
+There is an important asymmetry to understand. Making the camera **reachable from** the tailnet (browsing to it, VAPIX, SSH from another tailnet node) works on every build. The harder direction is the camera **reaching out to** a tailnet peer, for example mounting an SMB/CIFS network share hosted on another node. How well this works depends on which build you use.
+
+### Why the build matters
+
+| Build | Networking mode | Camera-initiated access to tailnet peers |
+|---|---|---|
+| Non-root (`aarch64`, `armv7hf`) and `armv7hf_acap3` | `--tun=userspace-networking` (no kernel `tailscale0` interface) | Only through the local **SOCKS5 / HTTP proxies**, and only for **proxy-aware** apps. Firmware system services (the SMB share client, NTP, etc.) are proxy-unaware, so they **cannot** reach a peer's `100.x` Tailscale IP directly. |
+| **ROOT** (`aarch64_root`, `armv7hf_root`) | Kernel networking with a real `tailscale0` interface | Peer `100.x` IPs are routable at the OS level, so firmware services **can** connect directly. Enable **Accept Routes** to also reach subnets behind other nodes. |
+
+In short: on non-root builds the proxies cover apps that know how to use a proxy, but a system feature like "add network share" opens a raw socket that never touches the tunnel. The ROOT build is the clean way to let the camera *consume* tailnet services.
+
+### Plan B: reverse-SSH tunnel
+> **Requires root on the camera.** Port 445 is privileged, so binding it needs a root-capable build (e.g. developer certificates installed).
+
+If you cannot use the ROOT build but still need the camera to mount a share on a machine that is on your tailnet, you can make the remote share appear **local** to the camera with a reverse SSH tunnel. Because the destination becomes `127.0.0.1`, the proxy-unaware SMB client never has to route over the tailnet.
+
+From a computer that has both the share and tailnet access to the camera:
+
+```bash
+# Forward the camera's local port 445 back to the SMB share on this machine
+ssh -R 445:localhost:445 root@<camera-tailscale-ip>
+```
+
+Then, in the camera's **System → Storage → Add network share** dialog, use `127.0.0.1` as the share host and connect.

+## Roadmap
+
+### AXIS OS 13 Preparation
+
+AXIS OS 13 (scheduled for September 2026) introduces several breaking changes that affect all ACAP applications. The following items are required to maintain compatibility. See the full [AXIS OS 13 breaking changes](https://www.axis.com/for-developers/news/AXIS-OS-13-breaking-changes) announcement for details.
+
+- [ ] **Recompile for 64-bit time (Y2038)** - AXIS OS 13 switches to a 64-bit time interface. All ACAP apps must be recompiled against the updated SDK. Cameras with incompatible apps installed will roll back the OS upgrade rather than proceed.
+- [ ] **Sign the ACAP via the Axis ACAP Portal** - AXIS OS 13 removes the ability to install unsigned applications in production environments. The app must be submitted and signed through the official Axis ACAP Portal to remain installable.
+- [ ] **Migrate to Manifest Schema v2** - The `manifest.json` must use Manifest Schema v2, including an explicit declaration of compatible AXIS OS versions, to satisfy the new signing and compatibility requirements.
+- [ ] **Audit for executable stack usage** - Any ACAP compiled with an executable stack must be recompiled to comply with the new security restrictions in AXIS OS 13.
+- [ ] **Verify web UI works over HTTPS** - AXIS OS 13 enforces HTTPS-only connections by default. The bundled web UI must be tested to confirm it functions correctly under this constraint.
+
+### General Improvements
+
+- [x] **Accept DNS from tailnet toggle** - Add an opt-in setting to the settings page that passes `--accept-dns=true` to `tailscale up`. Defaults to off to prevent Tailscale from overriding `resolv.conf` on cameras that don't need MagicDNS.
+- [x] **Accept routes toggle** - Add an opt-in setting that passes `--accept-routes=true` to `tailscale up`, allowing the camera to use subnet routes advertised by other nodes in the tailnet.
+- [ ] **Switch to tiny-tailscale binaries** - Evaluate replacing the bundled `tailscale` and `tailscaled` binaries with [tiny-tailscale](https://github.com/iamromulan/tiny-tailscale) builds. These combine both into a single binary, strip unused features, and are significantly smaller (~43% reduction), reducing install size and memory footprint across all architectures.

+ * ACAP parameter bridge for Tailscale VPN (userspace variant).

+ * Responsibilities:
+ *  1. Read Tailscale parameters from the ACAP parameter store (axparameter).
+ *  2. Write them to CONFIG_FILE so the shell script can source them.
+ *  3. Launch the shell script (Tailscale_VPN_run) as a child process.
+ *  4. On any parameter change: rewrite CONFIG_FILE and do a full stop+restart
+ *     of the child so the new config is picked up.
+ *     Rapid changes within 300 ms are coalesced into a single restart.
+ *  5. Watchdog: if the child exits unexpectedly, restart it.
