Refactored Settings UI (#65)

Summary of what we fixed:

  1. Added constructors to OpenAISettings and other provider classes
  2. Fixed import paths:
    - BaseProviderSettings: Logger path (already correct)
- BrowsingHistorySettings: Changed ../../../../ to ../../../../../ for
Common import
3. Added type casts for refreshModelSelectOptions calls in GroqSettings
and LiteLLMSettings
  4. Added override modifier to OpenRouterSettings.cleanup()
  5. Added static method updateOpenRouterModels to SettingsDialog
6. Re-exported isVectorDBEnabled from SettingsDialog for backward
compatibility
7. Fixed Dockerfile to delete out/Default before rebuilding, ensuring
new files in BUILD.gn are recognized
