KIN-103: Добавить поддержку worktrees_enabled в PATCH /api/projects/{project_id}

- Добавлено поле worktrees_enabled: bool | None = None в класс ProjectPatch
- Добавлена проверка в has_any для обнаружения изменений
- Добавлена обработка поля при преобразовании в целое число для БД

DB schema и runner уже содержат поддержку worktrees_enabled.
GET /api/projects/{id} возвращает поле автоматически через SELECT *.
