exportCtrl mapped every export failure to 500 Internal Server Error, so
requesting a backup for a non-existent site (e.g. wrong -s/--site) came
back as a misleading 500 instead of a client error — inconsistent with
the rest of the admin/public API, which returns 400 + ErrSiteNotFound
for site-lookup failures.
Add an engine.ErrSiteNotFound sentinel (wrapped at the bolt db-lookup so
the existing "site %q not found" message is unchanged) and map it to 400
+ rest.ErrSiteNotFound in exportCtrl; genuine internal failures (gzip
close/write) still return 500.
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.
