chore(biome): disable useImportType for apps/api

Biome's useImportType rule rewrites runtime value imports to
type-only imports. NestJS DI relies on reflect-metadata reading
constructor parameter types at runtime, so type-only imports
break dependency resolution and crash the API at startup
(see fix in 0774444).

Disable the rule for apps/api/**:
- Root biome.json: apps/api/** override (root-cwd lint passes)
- apps/api/biome.json: extends root + override (workspace-cwd
  lint, the path Turbo/CI takes)

Both paths are needed because Biome resolves the nearest config
to the cwd and the include globs are interpreted relative to it.
