refactor(app-marketplace): rename featured to vetted (#22674)

## What

Renames the application-registration "featured" flag to "vetted" across
the backend, frontend, GraphQL schema/DTOs, and the marketplace UI.

"Vetted" better describes what the flag actually does today: it marks an
app as reviewed and approved by the Twenty team (a trust signal), rather
than "featured" which reads as spotlighting/promotion. The admin toggle
description was already "Mark this app as reviewed and approved".

## How

- Renamed `isFeatured` -> `isVetted` on the `ApplicationRegistration`
entity, DTOs (`MarketplaceApp`, `MarketplaceAppDetail`,
`UpdateApplicationRegistrationPayload`), services, GraphQL fragments,
and the settings/admin UI (labels: "Featured" -> "Vetted", "Featured
only" -> "Vetted only", etc.).
- Renamed the `MARKETPLACE_FEATURED_APPLICATIONS` constant/file to
`MARKETPLACE_VETTED_APPLICATIONS`.
- Regenerated GraphQL client artifacts (`generated-metadata`,
`generated-admin`, `twenty-client-sdk`).

### Database

The `isFeatured` column is renamed in place to `isVetted` via a single
2.20 fast instance command (`ALTER TABLE ... RENAME COLUMN`). No new
column, no data-copy backfill.

- Since all 2.19 commands (including the existing `isFeatured` backfill)
complete before any 2.20 command runs, the rename carries over the
values that backfill set.
- The entity uses `@WasRenamedInUpgrade` so the upgrade-aware layer
queries the old column name until the rename step runs during an
upgrade.

## Testing

- `nx typecheck` and `nx lint:diff-with-main` pass for twenty-server and
twenty-front.
- Ran `database:reset` on a fresh dev DB: the 2.19 `isFeatured` backfill
runs first, then the 2.20 rename; the column ends up as `isVetted` (and
`isFeatured` no longer exists), values preserved.
- Booted the server: the `@WasRenamedInUpgrade` decorator validates
against the upgrade sequence, and GraphQL introspection confirms all
four types expose `isVetted` and none expose `isFeatured`.
- Ran the three `graphql:generate` configs and the SDK metadata client
generator so the committed generated files match the generator output
(field ordering included).

## Notes

- The `api-breaking-changes` check flags the removal of the `isFeatured`
GraphQL field — that is expected and inherent to this rename.
- Translation catalogs (`locales/`) are intentionally not touched here
since they are managed via Crowdin; new English strings render via
Lingui's default-message fallback until translated.
