Rebuild AgentCompany-New renderer to match design spec

- Port design tokens, sidebar, topbar, and icons to inline SVG set
- Rewrite each page (Home/Team/Work/Chat/Files/Approvals/Social/Settings)
  to drive real snapshot data and match the bento, kanban, three-pane chat,
  file tree + pinned cards, approval queue, social schedule + calendar,
  and settings sub-nav layouts
- Split Chat and Settings into per-concern subcomponents so every file
  stays under 500 lines
- Add schema v4 for pinned files and scheduled posts plus IPC + service
  wiring; cover new behavior in unit tests
- Update onboarding labels and Hire form to remove ambiguity for the
  expanded e2e suite (all settings tabs + 8 routes at 1280 and 980)
