feat: redesign View tab and fix Annotate/tab order

- Redesign View ribbon tab with 8 groups matching AutoCAD layout:
  Viewport Tools (UCS Icon, ViewCube, Navigation Bar),
  Navigate, Model Viewports (Viewport Configuration, Named, Join, Restore),
  Visual Style (dropdown), Projection, Preset,
  Palettes (Tool Palettes, Properties, Sheet Set Manager),
  Interface (File Tabs, Layout Tabs, Tile Horiz/Vert, Cascade)
- Add Extract Data and Link Data tools to Annotate → Tables group
- Fix tab order to Home → Insert → Annotate → View → Manage via build.rs PRIORITY list
- Add 17 new SVG icons for all new commands
