🕵️ refactor: Optimize Message Search Performance (#9818)

* 🕵️ feat: Enhance Index Sync and MeiliSearch filtering for User Field

- Implemented `ensureFilterableAttributes` function to configure MeiliSearch indexes for messages and conversations to filter by user.
- Updated sync logic to trigger a full re-sync if the user field is missing or index settings are modified.
- Adjusted search queries in Conversation and Message models to include user filtering.
- Ensured 'user' field is marked as filterable in MongoDB schema for both messages and conversations.

This update improves data integrity and search capabilities by ensuring user-related data is properly indexed and retrievable.

* fix: message processing in Search component to use linear list and not tree

* feat: Implement user filtering in MeiliSearch for shared links

* refactor: Optimize message search retrieval by batching database calls

* chore: Update MeiliSearch parameters type to use SearchParams for improved type safety
