feat: Add compact table views with advanced filtering and batch operations

- Enhanced Flutter web app management in PowerShell scripts
  - Added Flutter web server to start-services.ps1 as 4th service
  - Updated stop-services.ps1 to stop Flutter web server
  - Improved service orchestration and startup sequence

- Implemented server caching for improved resilience
  - Added ServerCacheService for browser localStorage caching
  - Server lists persist across service restarts
  - Automatic fallback to cached data when API unavailable
  - Action picker categories always visible regardless of server status

- Redesigned Action Mappings view with compact table layout
  - Replaced card-based ListView with DataTable for higher density
  - Added real-time search across name, input, output, description
  - Implemented multi-filter support (status: enabled/disabled)
  - Added column sorting (name, input, output, status, executions)
  - Batch operations: select all/multiple, batch delete
  - Reduced row height from ~120px to 56px for better overview

- Redesigned Servers Management view with compact table layout
  - Replaced card-based ListView with DataTable
  - Added search by alias, host, user
  - Multi-filter support (type: all/G-Core/GeViScope, status: all/enabled/disabled)
  - Column sorting (alias, host, user, type, status)
  - Batch operations: select all/multiple, batch delete
  - Color-coded type and status badges

- Improved action picker dialog for GSC/G-Core actions
  - GSC and G-Core categories always visible
  - Server validation with clear error messages
  - Fixed duplicate checkbox issue in table headers
  - Debug logging for troubleshooting server parameter issues
