feat(app.js, i18n): enhance Gemini API key management with base URL support

- Updated the CLIProxyManager to handle both API keys and optional base URLs for Gemini.
- Added new input fields in the modal for base URL entry during key addition and editing.
- Updated internationalization strings to include labels and placeholders for the base URL in both English and Chinese.
- Improved key normalization and rendering logic to accommodate the new structure.
