fix(team_process): Clean up stuck processing owners on startup and batch completion

- Add CleanupStuckProcessingOwners database method to reset owners stuck in processing status back to valid state
- Call cleanup routine on application startup to recover from previous abnormal exits
- Call cleanup routine after batch processing completes to ensure no orphaned processing states remain
- Add markOwnerResult calls in processSingleTeam when team invitations are full to properly track owner status
- Prevents owners from being permanently stuck in processing state due to unexpected shutdowns or errors
