Fix getFiles query logic to prevent duplicate records

[m7moudabdel7mid]

This pull request fixes an issue in the getFiles method where the query logic caused duplicate file records due to improper condition grouping.

Before the Change
The query structure was:
select * from `media` where `id` not in (?, ?) and `type` in (?) or `type` LIKE ? order by `created_at` desc

After the Change
The query structure is now:
select * from `media` where `id` not in (?, ?) and (`type` in (?) or `type` LIKE ?) order by `created_at` desc

This ensures all conditions are properly applied, preventing duplicates.
