🕰️ fix: Preserve updatedAt Timestamps During Meilisearch Batch Sync (#12084)

refactor: Add timestamps option to updateMany in createMeiliMongooseModel

Updated the updateMany call in createMeiliMongooseModel to include a timestamps option set to false, ensuring that the operation does not modify the document’s timestamps during the indexing process. This change improves the accuracy of document state management in MongoDB.

test: Add tests to ensure updatedAt timestamps are preserved during syncWithMeili

Introduced new test cases for the processSyncBatch function to verify that the original updatedAt timestamps on conversations and messages remain unchanged after synchronization with Meilisearch. This enhancement ensures data integrity during the indexing process.

docs: Update comments in createMeiliMongooseModel to clarify timestamp preservation

Enhanced comments in the createMeiliMongooseModel function to explain the use of the { timestamps: false } option in the updateMany call, ensuring that original conversation/message timestamps are preserved during the indexing process. This change improves code clarity and maintains the integrity of document timestamps.

test: Enhance Meilisearch sync tests to verify updatedAt timestamp preservation

Added assertions to ensure that the updatedAt timestamps of documents remain unchanged before and after synchronization with Meilisearch. This update improves the test coverage for the syncWithMeili function, reinforcing data integrity during the indexing process.
