Remove redundant @Repository annotations

Remove unnecessary @Repository annotations and corresponding unused imports from proprietary JPA repository interfaces. Files updated: ResourceGrantRepository, TeamLabelsRepository, ProcessedFileRepository, PolicyRepository, TeamMembershipRepository. No behavioral change — Spring Data auto-detects JpaRepository interfaces; this is a cleanup to remove static noise and unused imports.
