feat: support manual model input and sync provider catalogs

- Allow manual model name input when adding custom providers (NSelect tag mode)
- Sync provider model catalogs with Hermes _PROVIDER_MODELS
- Add new providers: kimi-coding-cn, moonshot, arcee
- Fix provider key naming to match Hermes (kilo→kilocode, vercel→ai-gateway, etc.)
- Ensure custom_providers from config.yaml always appear in available-models
- Append configured default model to model list if not in catalog
- Fix provider deletion with case-insensitive key matching
- Add selectOrInput i18n key to all 8 locales

Closes #24
