Add i18n vendor overlays and dynamic bundling

- Add opt-in vendor overlays under src/env/locales/<env>
  (and optional variant), merged on top of base locales at runtime.
- Auto-discover and bundle all base locale JSON files
  in src/locales/.
- Example: move dump type labels under pageDumps.dumpTypes;
  read vendor-only dump labels from overlays.
- Docs: update i18n guidelines and env README (formatting fixes).
- Tests: add focused unit tests for overlays and locale aliases.

Tested:
- Unit: i18n.locale-alias.spec.js, i18n.vendor.spec.js (passing)
- Manual: Verified dynamic locale discovery and overlay merge in UI
