[FEATURE REQUEST] Add search/filter bar to torrent file selection screen

[Velegand]

Is your feature request related to a problem? Please describe.
When adding a torrent that contains hundreds of files, it's difficult and time-consuming to manually scroll through the entire file list to find or select certain files for download. Currently, there is no search or filter option on the file selection screen, making it hard to select only the files you want (for example, specific episodes, video files, or files above a certain size).

Describe the solution you'd like
Add a search/filter bar to the torrent file selection screen (the UI where you choose which files to download from a torrent). The feature should allow users to:

• Search files by name
• Filter by file extension/type (e.g., only show video, audio, or subtitle files)
• Filter by file size (e.g., only show files above a size threshold)
• (Optionally) allow quick selection/deselection of all files matching a filter

Describe alternatives you've considered

• Manually scrolling and selecting files one by one (impractical for large torrents)
• Existing filter features appear only in the downloads/folder view, not the torrent file picker

Additional context

• Feature is present in many other torrent apps
• Would greatly improve usability for users who download large torrents with many files
• Version tested: 1.7.0 (no search/filter input visible in torrent file selection screen)
