Add visual feedback for Move to Ready action (#165)

* feat(orchestrator): add visual feedback when moving jobs to Ready

- Added `toast.message("Moving job to Ready...")` in `OrchestratorPage.tsx` for single item keyboard shortcut action.
- Added `toast.message("Moving jobs to Ready...")` in `useBulkJobSelection.ts` for bulk `move_to_ready` action.
- Updated `OrchestratorPage.test.tsx` to verify the toast notification.

This addresses the issue where pressing 'R' provided no visual feedback until the action completed.

* fix(orchestrator): remove accidental db files

Removed `orchestrator/data/jobs.db`, `orchestrator/data/jobs.db-shm`, and `orchestrator/data/jobs.db-wal` which were accidentally created during testing.

* fix(orchestrator): remove accidental root sqlite.db

Removed `orchestrator/sqlite.db` which was also accidentally created.
