Use whereLike for case-insensitive search

[tabuna]

This updates search functionality to use the whereLike method, introduced in Laravel v11.17.0, for performing case-insensitive searches. For Laravel versions below 11.17.0, the existing implementation using like is retained.

The whereLike method adapts to the specifics of different databases:

• PostgreSQL: Uses ilike for case-insensitive search.
• MySQL: Uses like.
• SQLite: Uses like.
• SQL Server: Behavior depends on the column/database collation.
