Add repository history feature to store and suggest previously used repositories (#18)

- Add repository_history table migration with repo_type, repo_path, use_count, last_used_at
- Add RepositoryHistoryEntry model and CRUD database functions
- Create API endpoints: GET/POST/DELETE /api/v1/repository-history, GET /api/v1/repository-history/suggestions
- Update add_remote_repository and add_local_repository handlers to automatically track history
- Update frontend API with repository history types and functions
- Add Repository History section to Settings page with list of entries and delete functionality
- Add suggestions dropdown to RepositoryPanel when entering new repository URL/path
- Suggestions filter by repo type (remote vs local) and match on user input

Test plan:
- Add a remote repository to a contract - verify it appears in Settings history
- Add a local repository to a contract - verify it appears in Settings history
- Add same repository again - verify use_count increments, not duplicate
- When adding new repository, verify suggestions appear based on history
- Delete a history entry from Settings - verify it's removed
- Verify suggestions only show matching type (remote for remote, local for local)
