fix: improve model list layout in ProviderCard (#311)

* fix: add LongCat provider, OpenRouter free models, model list in cards

- Add longcat to PROVIDER_ENV_MAP and PROVIDER_PRESETS
- Add freeOnly param to fetchProviderModels, use for OpenRouter
- Show model list in ProviderCard with count
- Fix qq.ts import.meta.url → __dirname for CJS compat
- Add zh/en i18n keys for model count display

* fix: improve model list layout in ProviderCard

- Change models-list from max-height to fixed height (100px)
- Add align-content: flex-start to prevent vertical spacing
- Optimize gap to 4px vertical, 6px horizontal
- Fix model-tag height to 20px to prevent background stretching
- Use inline-flex for better tag alignment
