feat(deeplink): add Claude model fields support and enhance import dialog

- Add Claude-specific model field support in deeplink import:
  * Support model (ANTHROPIC_MODEL) - general default model
  * Support haikuModel (ANTHROPIC_DEFAULT_HAIKU_MODEL)
  * Support sonnetModel (ANTHROPIC_DEFAULT_SONNET_MODEL)
  * Support opusModel (ANTHROPIC_DEFAULT_OPUS_MODEL)
  * Backend: Update DeepLinkImportRequest struct to include optional model fields
  * Frontend: Add TypeScript type definitions for new model parameters

- Enhance deeplink demo page (deplink.html):
  * Add 5 new Claude configuration examples showcasing different model setups
  * Add parameter documentation with required/optional tags
  * Include basic config (no models), single model, complete 4-model, partial models, and third-party provider examples
  * Improve visual design with param-list component and color-coded badges
  * Add detailed descriptions for each configuration scenario

- Redesign DeepLinkImportDialog layout:
  * Switch from 3-column to compact 2-column grid layout
  * Reduce dialog width from 500px to 650px for better content display
  * Add dedicated section for Claude model configurations with blue highlight box
  * Use uppercase labels and smaller text for more information density
  * Add truncation and tooltips for long URLs
  * Improve visual hierarchy with spacing and grouping
  * Increase z-index to 9999 to ensure dialog appears on top

- Minor UI refinements:
  * Update App.tsx layout adjustments
  * Optimize McpFormModal styling
  * Refine ProviderCard and BasicFormFields components

This enables users to import Claude providers with precise model configurations via deeplink.
