Trim redundant comments and correct stale ones

param_bridge wrote params.conf unquoted and the run script sourced it and ran tailscale up through eval, so a setting containing $(...) executed (as root in the ROOT variant). Values are now single-quoted shell literals and the up command is built as an argument list. AdvertiseRoutes also tolerates spaces after commas, which previously dropped every route. Verified on a P3288-LV (OS 12.11).
