Summary of Changes

This is a clean, fresh PR implementing the complete File Movement and Barcode Scanning system for Case Central (version-16):

• Single Document Lifecycle:
  • Unified outgoing and incoming movement tracking in File Movement.
  • Mutually exclusive Giver and Receiver employee validation.
• Physical & Barcode Scanning:
  • Full support for hardware USB barcode scanners as well as camera-based scanning via Html5Qrcode.
  • Auto-resolves Matter ID, Case ID, Case Barcode, or physical file stickers.
• Clean Child Schema:
  • File Movement Item: Link to Matter, Link to Case, and Barcode. Unnecessary legacy fields permanently removed.
  • Safe controller handling for documents created with or without barcode stickers.
• Multi-Case Selection Modal:
  • Interactive selection prompt when dispatching or returning files for a Matter that has multiple linked Case files.
• Automated Return & Missing Files Tracking:
  • Auto-compares scanned incoming files against outgoing files and updates status (Open -> Missing Files / Received).
  • Automatically resets linked Matter status back to Open once all files are returned.
• Strict Scope:
  • Exactly 12 files representing the 3 DocTypes (File Movement, File Movement Item, Missing File Items).
  • Zero modifications to unrelated DocTypes (Matter, Case, Caveat, Workspace, Dock, or settings).
