- Imported `getQueryParam` function from `src/utils/queryUtils`
- Added `loadQuery` function to retrieve and set query parameter as textarea value
- Added button to trigger `loadQuery` function

- Changed API model names from 'pplx-70b-online' to 'llama-3.1-sonar-huge-128k-online' in PerplexityBot and PerplexityLabsBot classes.
- Improved `getQueryParam` function to support hash-based routing for query parameters.
- Added `loadQuery` function in ChatMessageInput to automatically load query parameters into the textarea on component mount.

- Refactored ClaudeApiBot to support both 'claude-3' and 'claude-3-5-sonnet-latest' models with dynamic endpoint selection.
- Updated ClaudeWebBot to use 'claude-3-5-sonnet-latest' as the default model and adjusted error handling for model restrictions.
- Modified PoeWebBot to reflect the new 'claude-3-100k' model.
- Updated settings components to align with the new model names and ensure correct configuration handling.
- Adjusted user configuration service to default to 'claude-3' models across relevant enums and settings.

- Commented out the premium validation and activation logic in `use-premium.ts` and `premium.ts` for testing purposes.
- Updated `fetchPurchaseInfo` and `checkDiscount` functions in `server-api.ts` to return empty objects instead of making API calls.
- This change is intended for debugging and will be revisited for reimplementation.
