feat: add maxSyncPeriod configuration to TFS settings

- Introduced maxSyncPeriod option in TfsConfigForm for user-defined synchronization duration.
- Updated TfsService to filter pull requests based on the configured maxSyncPeriod.
- Enhanced TfsPullRequest type to include 'rejected' status for better PR management.
- Set default maxSyncPeriod to '90d' in user preferences and TFS configuration.
