feat(web/ui): refactor component inline styles into utility classes

Pass 2 of the web UI spacing/typography/visual-rhythm rework.

- Add layout, spacing, typography, visual, card, and component utilities
- Add form-section, form-row, form-help, text-error, alert-success
- Unify .form-group and .form-field; add .status-badge family
- Alias legacy button classes to .btn primitives
- Refactor ToolTypeListSidebar and ConfigProfileListSidebar to use .sidebar
  and var(--sidebar-width) instead of hardcoded 280px
- Refactor ToolTypeEditorPanel, ConfigProfileEditorPanel,
  git-mount-editor, and manifest-editor to use utility classes

Quality gates: npm run typecheck, npm run lint, npm run build pass.
Inline style blocks in target components reduced from 198 to 11.
