beabigegg 3bdc6ff1c9 feat: implement 8 OpenSpec proposals for security, reliability, and UX improvements 
## Security Enhancements (P0)
- Add input validation with max_length and numeric range constraints
- Implement WebSocket token authentication via first message
- Add path traversal prevention in file storage service

## Permission Enhancements (P0)
- Add project member management for cross-department access
- Implement is_department_manager flag for workload visibility

## Cycle Detection (P0)
- Add DFS-based cycle detection for task dependencies
- Add formula field circular reference detection
- Display user-friendly cycle path visualization

## Concurrency & Reliability (P1)
- Implement optimistic locking with version field (409 Conflict on mismatch)
- Add trigger retry mechanism with exponential backoff (1s, 2s, 4s)
- Implement cascade restore for soft-deleted tasks

## Rate Limiting (P1)
- Add tiered rate limits: standard (60/min), sensitive (20/min), heavy (5/min)
- Apply rate limits to tasks, reports, attachments, and comments

## Frontend Improvements (P1)
- Add responsive sidebar with hamburger menu for mobile
- Improve touch-friendly UI with proper tap target sizes
- Complete i18n translations for all components

## Backend Reliability (P2)

- Add Redis fallback mechanism with message queue
- Add blocker check before task deletion

## API Enhancements (P3)
- Add standardized response wrapper utility
- Add /health/ready and /health/live endpoints
- Implement project templates with status/field copying

## Tests Added
- test_input_validation.py - Schema and path traversal tests

Change: Add Permission Enhancements for Manager and Cross-Department Access

Why

Department managers cannot view their subordinates' workload data, preventing effective resource allocation decisions. Additionally, cross-department project collaboration is hindered because project members from other departments may be denied access.

What Changes

  • Enable department managers to view workload data of their department members
  • Add project membership model to support cross-department collaboration
  • Enhance access control to check project membership in addition to department

Impact

  • Affected specs: resource-management
  • Affected code:
    • backend/app/api/workload/router.py - Manager access logic
    • backend/app/middleware/auth.py - Access control checks
    • backend/app/models/ - New project_members model (optional)
