🔍 feat: Add SearXNG for Web Search and Enhance ApiKeyDialog (#8242)

* 🔍 feat: Add SearXNG Web Search support and enhance ApiKeyDialog

- Updated WebSearch component to include authentication data for web search functionality so it won't show badge after being revoked
- Refactored ApiKeyDialog to streamline provider, scraper, and reranker selection with new InputSection component
- Added support for SearXNG as a search provider and updated translation files accordingly
- Improved form handling in useAuthSearchTool to accommodate new API keys and URLs

* 📜 chore: remove unused i18next key

* 📦 chore: address comments (swap API key and URL fields in SearXNG config, change input fields to 'text' from 'password'

* 📦 chore: make URL fields go first in ApiKeyDialog

* chore: bump @librechat/agents to v2.4.52

* ci: update webSearch configuration to include searxng fields in AppService.spec.js
