Fix Apps UI: replace 'Managed' label with actual app name and unify app icons (#19897)

## Summary

- The Data Model table was labeling core Twenty objects (e.g. Person,
Company) as **Managed** even though they are part of the standard
application. This PR teaches the frontend to resolve an `applicationId`
back to its real application name (`Standard`, `Custom`, or any
installed app), and removes the misleading **Managed** label entirely.
- Introduces a single, consistent way to render an "app badge" across
the settings UI:
- new `Avatar` variant `type="app"` (rounded 4px corners + 1px
deterministic border derived from `placeholderColorSeed`)
- new `AppChip` component (icon + name) backed by a new
`useApplicationChipData` hook
- new `useApplicationsByIdMap` hook + `CurrentApplicationContext` so the
chip can render **This app** when shown inside the matching app's detail
page
- Reuses these primitives on:
- the application detail page header (`SettingsApplicationDetailTitle`)
  - the Installed / My apps tables (`SettingsApplicationTableRow`)
  - the NPM packages list (`SettingsApplicationsDeveloperTab`)
- Backend: exposes a minimal `installedApplications { id name
universalIdentifier }` field on `Workspace` (resolved from the workspace
cache, soft-deleted entries filtered out) so the frontend can resolve
`applicationId` -> name without N+1 fetches.
- Cleanup: deletes `getItemTagInfo` and inlines its tiny
responsibilities into the components that need them, matching the
`RecordChip` pattern.
