style: align widget surfaces with ChatGPT

[Chillizu]

Summary

• refresh CatDesk widget surfaces to better match ChatGPT's inline tool-card visual hierarchy
• use lighter borders, compact spacing, rounded panels, and UI typography while keeping code/diff output monospace
• soften token/cost metadata and remove the heavy hover/glow treatment
• preserve responsive behavior and light/dark theme styling

Scope

This is a presentation-only change in src/widget/catdesk_dashboard.html; tool payloads and MCP behavior are unchanged.

Verification

• manually exercised CatDesk widget states for read, write, edit, delete, search, run_command, start_command, poll_command, cancel_command, and catdesk_instruction in ChatGPT
• verified light/dark rendering in ChatGPT
• cargo test --release: 218 passed, 0 failed
• git diff --check: clean

Note: repository-wide cargo fmt --check still reports the pre-existing formatting difference in src/browser.rs on main; this PR only changes the widget HTML.

Summary by CodeRabbit

• Style
  • Updated the CatDesk widget with a refreshed light visual theme and automatic dark-mode support.
  • Replaced monospace typography with a modern sans-serif font.
  • Restyled panels, controls, search areas, file details, and completion views with neutral surfaces, rounded corners, and subtle shadows.
  • Improved token statistics layout and responsiveness on narrower screens.
  • Updated widget resources so the latest visual changes load reliably.
