The store tests stored timestamps with time.Local in their fixtures and
asserted equality against returned values that the engine round-trips
through UTC. assert.Equal compares zone identity, so on UTC machines
(CI, most cloud envs) Local==UTC and the tests passed; on a developer
machine in any other timezone (here BST, UTC+1) TestService_Put,
TestService_List, TestBoltDB_InfoPost, TestBoltDB_InfoList and several
others would fail with same wall-clock numbers but mismatched zones.
Replace time.Local with time.UTC across store/comment_test.go,
store/formatter_test.go, store/service/service_test.go,
store/engine/bolt_test.go, store/engine/engine_test.go. Production code
is untouched.
Apply go fix ./... analysers (Go 1.26) across backend and examples:
- interface{} → any (type alias, no behaviour change)
- for i := 0; i < N; i++ → for range N / for i := range N
- slices.Contains / slices.ContainsFunc replacing manual loops
- strings.SplitSeq replacing strings.Split in range (avoids allocation)
- strings.CutPrefix replacing HasPrefix+TrimPrefix
- min() replacing manual if/else
- fmt.Appendf replacing []byte(fmt.Sprintf(...))
- strings.Builder replacing string += concatenation
- wg.Go(func(){}) replacing wg.Add(1)/go/wg.Done() pattern
- removed redundant ii := i loop variable copies (unnecessary since Go 1.22)
omitempty on struct-typed JSON fields: go fix removed omitempty from
struct-typed fields (time.Time, PostInfo, UserDetailEntry) because
encoding/json's omitempty never applied to struct types — it was always
a no-op. Kept as bare tags (no omitzero replacement) to preserve the
existing serialisation behaviour.
Replace strings.Split(RemoteAddr, ":") with net.SplitHostPort for correct
IPv6 address extraction in vote deduplication and comment IP tracking.
Harden image proxy: add SSRF-safe transport blocking private/reserved IPs
at connection time with DNS rebinding protection, sanitize error messages
to prevent information leakage, add response size limit via io.LimitReader.
Fix shadowed error variables in BlockedUsers, SetTitle, and Delete methods.
Exclude gosec taint analysis false positives at linter config level.
Fixes the following conversion problem for BlockedUser:
```
panic: interface conversion: interface {} is map[string]interface {},
not store.BlockedUser [recovered]
```
Resolves#1475.
