Remove Favorite and FavoriteFolder from workspace schema (#19536)

## Summary

- Removes all workspace schema definitions for `Favorite` and
`FavoriteFolder` entities, which have been fully migrated to
`NavigationMenuItems`
- Deletes 26 standalone files including workspace entities, NestJS
modules, services, listeners, jobs, standard application builders (field
metadata, views, view fields, view field groups, indexes, page layouts),
mocks, and integration tests
- Cleans up ~40 modified files: removes `favorites` relation from 10
workspace entities and their field metadata utils, removes entries from
all builder maps, shared constants (`STANDARD_OBJECTS`,
`CoreObjectNameSingular`, `DEFAULT_RELATIONS_OBJECTS_STANDARD_IDS`), SDK
default relations, AI tool filtering, and standard object icons
