Title: feat: integrate annotation management system and align with upstream refactoring

Description:
This PR introduces the Project Manager module for handling large-scale scientific image annotation tasks. It also includes critical fixes to align the codebase with the recent upstream/main refactoring (specifically the sunset synanno changes).

Key Changes:

Module Integration: Added ProjectManager for task distribution, tracking, and high-priority assignments.

Upstream Alignment: * Cleaned up deprecated component references (WorkflowSelector, ProofReading, WormErrorHandling, EHTool) following the upstream synanno sunset.

    Reorganized view directory structures to match the new official module layout.

Bug Fixes: * Resolved CORSMiddleware configuration conflicts in server_api/main.py.

    Fixed module import paths in Views.js and MaskProofreading.js caused by directory restructuring.

Backend Support: Updated the API server to handle dynamic task queries and JSON-based persistence.

Verification:

npm run build passes successfully.

python3 -m py_compile verifies backend syntax.

Manual test: Verified ProjectManager displays tasks and correctly handles assignee filtering.

Key Changes:
Standardized Data Pooling: Implemented dataReader.js and updated

ProjectManagerContext.js
to decouple the UI from specific file paths, allowing for "pooled" metadata resolution.
External Metadata Resolution: The backend now supports dynamic metadata loading via the PROJECT_METADATA_JSON and DATA_ROOT_EM environment variables.
Ingestion Pipeline: Added

scripts/ingest_data.py
, an industrial-grade crawler that recursively scans storage for .h5 files, automatically excluding development artifacts (like .venv).
Frontend Stabilization: Resolved build failures by Safely commenting out sunsetted components (ProofReading, EHTool) and setting the Project Manager as the default application entry point.
Session Persistence: Integrated localStorage to ensure Admin/Worker login sessions persist across browser restarts.
Verification Plan

1. Ingestion & Storage Sync
   Set the following environment variables:
   DATA_ROOT_EM: Path to your directory containing .h5 files.
   PROJECT_METADATA_JSON: Path to where you want the metadata "database" (JSON) to reside.
   Start the app and log in as admin (password: admin123).
   Navigate to Project Manager > Volume Tracker.
   Click "Sync with Storage".
   Verify: The "Volume List" should now reflect your physical files (e.g., "228 matching" for the test dataset) and the global progress counts should update accordingly.
2. RBAC & Persistence
   Log in as any worker (e.g., alex / alex123).
   Verify that the "Sync with Storage" button and sensitive Admin tabs are hidden.
   Refresh the browser and verify the session remains active.
3. Frontend Integrity
   Run cd client && npm run build to ensure all "rescue" modifications in

Views.js
are syntactically correct.
Verify the Mask Proofreading tab displays the fallback "Disabled" state rather than crashing the application.
