feat(server): resolve app translations across remaining metadata resolvers (#22237)

## Summary

**PR 3/4** of the app-metadata-translations stack. Extends runtime
translation resolution to the remaining Twenty-rendered metadata types
so coverage is complete.

- New shared `MetadataTranslationResolverService.getApplicationCatalog({
applicationId, workspaceId, locale })` — the single seam for fetching an
app's per-locale catalog.
- Wired into the **page-layout tab**, **page-layout widget**,
**view-field-group**, **command-menu navigation item**, and **view
name** resolvers, each extended with an optional `applicationCatalog`
param (backward-compatible).

Together with PR 1/4 (object + field), this covers all seven
translatable metadata surfaces.

## Stack
Stacks on #22236 (PR 2/4). Base branch:
`claude/app-translation-2-sdk-manifest`.

## Verification note
`yarn install` could not complete in the remote dev environment, so
typecheck/lint/tests were not run locally — **CI is the source of
truth**.
