Modify /admin/config to show only database-set configurations, excluding database and network configs

- Modified analysis page to only show stats sidebar for admin users
- Enhanced /api/stats endpoint to include cluster information for admins
- Added GPU backend detection summary to stats
- Updated JavaScript to display comprehensive system and cluster stats
- Stats now show local resource usage and cluster status for administrators

Note: Full job-specific worker stats (showing resources from the machine executing each specific job) would require additional development to track job-to-worker mappings and implement worker resource reporting.

- Added --weight parameter to client connections (default: 100)
- Modified cluster master to prioritize GPU-enabled clients for job distribution
- GPU clients always get precedence over CPU-only clients
- When no GPU workers have required model, GPU clients still preferred for model distribution
- Client weights are combined with process weights for load balancing
- Higher weight = more jobs assigned to that client

Job distribution priority:
1. GPU clients with required model already loaded
2. CPU clients with required model already loaded
3. GPU clients (model will be sent)
4. CPU clients (model will be sent)

Within each category, clients are selected based on combined weight.

- Added --no-gpu command line flag
- When --no-gpu is specified or no GPUs are detected, local worker processes are not started
- This allows running vidai as a cluster master without local GPU processing
- Useful for dedicated cluster master nodes that only manage remote clients

- Add GPU detection utility functions in compat.py
- Modify vidai.py to detect GPUs at startup and configure backends
- Update cluster_client.py to detect GPUs and send capabilities to master
- Modify cluster_master.py to handle client capabilities and model distribution
- Update config.html template to dynamically show/hide backend options
- Update web.py config route to handle dynamic backend availability
- Add model file transfer functionality between master and clients
- Update worker processes to handle model downloads from master
- Test GPU detection and configuration
- Update API documentation for new capabilities

Features implemented:
- Automatic detection of NVIDIA CUDA and AMD ROCm GPUs
- Dynamic configuration of analysis/training backends based on available hardware
- Cluster clients report GPU capabilities to master
- Model distribution from master to clients when needed
- Admin config page hides unavailable backend options
- Updated API documentation reflecting new GPU detection capabilities

- Add --client mode with required --cluster-host, --cluster-port, --token options
- Optional --optimize and --flash for client mode
- Convert cluster communication from TCP to bidirectional websockets
- Implement file transfer placeholders for jobs and results
- Update cluster master to authenticate clients via cluster_token
- Add configuration page for managing cluster clients (placeholder)
- Update build scripts to include cluster components
- Add websockets to requirements
- Disable web/API interfaces in client mode

- Modified /api/analyze to return job_id immediately after file upload
- Added /api/result/{job_id} endpoint for checking job status
- Job status includes: queued (with queue position), processing, completed (with result), failed
- Analysis runs in background thread
- Updated API documentation with new async workflow and result endpoint examples

- Modified /api/analyze to accept file uploads for all users
- Restricted file_path parameter to admin users only
- Added chunked file upload support with upload_id, chunk_number, total_chunks
- Updated API documentation with file upload examples and chunked upload guide
- Files are temporarily stored and cleaned up after processing

- Added .container CSS rule to constrain content width to 1200px max-width
- Added auto margins for centering and 2rem side padding
- Now matches the layout constraints of dashboard and history pages

- Moved API documentation content inside standard container div like dashboard/history pages
- Updated header styling to work within container (rounded corners, padding, shadow)
- Maintained modern design while following consistent page layout patterns

- Added gradient headers with icons for both API docs
- Implemented card-based layout for endpoints
- Added color-coded method badges and parameter styling
- Enhanced code blocks with syntax highlighting colors
- Added responsive design for mobile devices
- Included FontAwesome icons for better visual hierarchy
- Used consistent color schemes (green for user API, red for admin API)

- Changed all remaining @require_admin to @admin_required
- All decorators now use the centralized utils.py versions

- Changed all @require_admin to @admin_required in admin.py
- Now uses the decorator from utils.py instead of auth.py

- Removed require_admin import from auth.py in admin.py
- Now uses admin_required from utils.py instead
- Prevents session access at import time

- Created vidai/utils.py with shared authentication decorators
- Removed duplicate decorator definitions from web.py, api.py, and admin.py
- Updated all modules to import decorators from utils.py
- Maintains consistent authentication logic across all modules

- Added admin_required decorator definition in api.py to fix NameError

- Added login_required decorator definition in api.py to fix NameError

- Created vidai/admin.py with Flask Blueprint for admin web routes
