refactor: extract shared auth dependencies (Task 3.1)
- Add get_owned_project() to auth/dependencies.py
- Remove duplicated _get_user() and _get_owned_project() from all routers
- Update tool_instances, git_repositories, projects, ssh_keys, users,
user_config, tool_types routers to use FastAPI dependency injection
- Route handlers now receive User/Project models via Depends() instead
of calling inline async helpers
Quality gates: Python syntax check (pass), no duplicated helpers (pass)
