feat(ui): enhance model select modal UX and modal traffic lights (#1111)

* feat(model-select-modal): highlight added models and support bulk selection

- Add addedModelValues prop to highlight already-added models with primary color
- Sort models alphabetically per provider, with added models floated to top
- Replace green highlight with primary brand color (orange #E56A4A)
- Use check icon (10px) inline with model name instead of check_circle
- Replace Done button with info bar explaining click-to-toggle behavior
- Add ProviderIcon to provider group headers replacing colored dot
- Import ProviderIcon, remove unused Button import

* feat(cli-tools): wire addedModelValues, onDeselect, and auto-save to model select modals

- Pass selectedModels as addedModelValues to ModelSelectModal in OpenCode and Copilot cards
- Add onDeselect handler to remove model from list on second click
- Set closeOnSelect=false to allow bulk model selection
- Remove manual setModalOpen(false) from onSelect callbacks
- Add saveModels() silent auto-save triggered on modal close (OpenCodeToolCard)
- Use useRef to track latest selectedModels in closure-safe way

* feat(modal): functional traffic light close button with hover icon and tooltip

- Make red dot a clickable button that closes the modal
- Show ✕ icon inside red dot on hover via group-hover opacity transition
- Gray out yellow and green dots (cursor-not-allowed, no tooltip)
- Increase dot size from w-3 h-3 to w-4 h-4
- Add Tooltip with brand-matched color #FF5F56 on red dot
- Remove X close button from modal header

* feat(tooltip): add color prop for themed tooltip backgrounds

* feat(i18n): add translations for model select info bar and close tooltip

- Add 'Click to add, click again to remove. Changes are saved automatically.' to all 32 locales
- Add 'Close' translation to all 32 locales

* fix(ui): address code review feedback on modal UX and auto-save

- Modal: remove showCloseButton prop, use showTrafficLights for header
  condition, hide traffic lights on mobile (hidden md:flex), add mobile
  X button (md:hidden) with aria-label, add aria-label and title on
  traffic light close button
- OpenCodeToolCard: validate activeModel membership before saving —
  fallback to models[0] or empty string; clear/reassign activeModel
  on deselect when removed model was the active one
- CopilotToolCard: add useRef + selectedModelsRef, add saveModels()
  using /api/cli-tools/copilot-settings, wire auto-save on modal close
- ModelSelectModal: fix JSX formatting — separate info bar closing div
  from Search comment onto its own line
