refactor(routes): move gallery domain into routes/gallery subpackage (#4903)
Move the gallery route domain into routes/gallery/ while preserving backward-compatible legacy import shims.
- app imports the canonical gallery route module
- canonical gallery route code imports canonical gallery helpers
- legacy gallery route/helper paths remain compatibility aliases
- add shim regression coverage for module identity and monkeypatch behavior
- repoint gallery source-introspection tests to the canonical paths
No intended behavior change.
