fix(unified search): back pressed

[alperozturk96]

• Tests written, or not not needed

Issue

When a user opens a file from Unified Search and then navigates back, the file list no longer shows the search results.
Instead, it resets to All files, even though the search view was the last active state.

How to reproduce?

1. Open Unified Search
2. Enter a search term that returns image and/or video results
3. Tap on any image or video to open it
4. Tap the back arrow (top-left) to return to the file list

Expected Result

The file list should return to the same search results shown before opening the file.

Actual Result

The file list resets to All files, losing the previous search state.
