refactor(forms): simplify and modernize form components

Comprehensive refactoring of form components to reduce complexity,
improve maintainability, and enhance user experience.

Provider Forms:
- CodexCommonConfigModal & CodexConfigSections
  * Simplified state management with reduced boilerplate
  * Improved field validation and error handling
  * Better layout with consistent spacing
  * Enhanced model selection with visual indicators
- GeminiCommonConfigModal & GeminiConfigSections
  * Streamlined authentication flow (OAuth vs API Key)
  * Cleaner form layout with better grouping
  * Improved validation feedback
  * Better integration with parent components
- CommonConfigEditor
  * Reduced from 178 to 68 lines (-62% complexity)
  * Extracted reusable form patterns
  * Improved JSON editing with syntax validation
  * Better error messages and recovery options
- EndpointSpeedTest
  * Complete rewrite for better UX
  * Real-time testing progress indicators
  * Enhanced error handling with retry logic
  * Visual feedback for test results (color-coded latency)

MCP & Prompts:
- McpFormModal
  * Simplified from 581 to ~360 lines
  * Better stdio/http server type handling
  * Improved form validation
  * Enhanced multi-app selection (Claude/Codex/Gemini)
- PromptPanel
  * Cleaner integration with PromptFormPanel
  * Improved list/grid view switching
  * Better state management for editing workflows
  * Enhanced delete confirmation with safety checks

Code Quality Improvements:
- Reduced total lines by ~251 lines (-24% code reduction)
- Eliminated duplicate validation logic
- Improved TypeScript type safety
- Better component composition and separation of concerns
- Enhanced accessibility with proper ARIA labels

These changes make forms more intuitive, responsive, and easier to
maintain while reducing bundle size and improving runtime performance.
