fix(ui): improve copilot sidebar logical order and remove redundancy

Changes:
- Reordered sidebar to follow logical flow:
  1. Setup: copilot-api binary → Integration enabled
  2. Auth: GitHub connection (only after binary installed)
  3. Daemon: status/port (only after authenticated)
- Removed redundant Config section (Model/Account already in right panel)
- Progressive disclosure: sections appear as prerequisites are met
