🧩 feat: Web Search Config Validations & Clipboard Citation Processing (#7530)

* 🔧 chore: Add missing optional `scraperTimeout` to webSearchSchema

* chore: Add missing optional `scraperTimeout` to web search authentication result

* chore: linting

* feat: Integrate attachment handling and citation processing in message components

- Added `useAttachments` hook to manage message attachments and search results.
- Updated `MessageParts`, `ContentParts`, and `ContentRender` components to utilize the new hook for improved attachment handling.
- Enhanced `useCopyToClipboard` to format citations correctly, including support for composite citations and deduplication.
- Introduced utility functions for citation processing and cleanup.
- Added tests for the new `useCopyToClipboard` functionality to ensure proper citation formatting and handling.

* feat: Add configuration for LibreChat Code Interpreter API and Web Search variables

* fix: Update searchResults type to use SearchResultData for better type safety

* feat: Add web search configuration validation and logging

- Introduced `checkWebSearchConfig` function to validate web search configuration values, ensuring they are environment variable references.
- Added logging for proper configuration and warnings for incorrect values.
- Created unit tests for `checkWebSearchConfig` to cover various scenarios, including valid and invalid configurations.

* docs: Update README to include Web Search feature details

- Added a section for the Web Search feature, highlighting its capabilities to search the internet and enhance AI context.
- Included links for further information on the Web Search functionality.

* ci: Add mock for checkWebSearchConfig in AppService tests

* chore: linting

* feat: Enhance Shared Messages with Web Search UI by adding searchResults prop to SearchContent and MinimalHoverButtons components

* chore: linting

* refactor: remove Meilisearch index sync from importConversations function

* feat: update safeSearch implementation to use SafeSearchTypes enum

* refactor: remove commented-out code in loadTools function

* fix: ensure responseMessageId handles latestMessage ID correctly

* feat: enhance Vite configuration for improved chunking and caching

- Added additional globIgnores for map files in Workbox configuration.
- Implemented high-impact chunking for various large libraries to optimize performance.
- Increased chunkSizeWarningLimit from 1200 to 1500 for better handling of larger chunks.

* refactor: move health check hook to Root, fix bad setState for Temporary state

- Enhanced the `useHealthCheck` hook to initiate health checks only when the user is authenticated.
- Added logic for managing health check intervals and handling window focus events.
- Introduced a new test suite for `useHealthCheck` to cover various scenarios including authentication state changes and error handling.
- Removed the health check invocation from `ChatRoute` and added it to `Root` for global health monitoring.

* fix: update font alias in Vite configuration for correct path resolution
