fix(ssh): Fixed the logic for handling font paths (#1093)

* fix(ssh): Fixed the logic for handling font paths

Correctly handles font filenames to avoid duplicate file extensions. Also optimized the logic for copying font files to ensure path accuracy.

Add an issue participant

* fix (Settings): Fixed the font clearing feature and added cache cleanup

On the SSH settings page, we fixed an issue where the font clearing feature failed to clear the cache and added logic to clear cached font files. Additionally, we changed the clearing operation to run asynchronously to ensure the page closes only after the operation is complete.

* fix: Check if the component has been mounted before popping the context

Avoid calling `context.pop()` when the component is unmounted, which causes an exception
