* Add Portuguese translations for permission error messages
Add error message translations for the permission check flow in the Portuguese locale, covering both check failures and request failures.
* Fix history audio playback on Linux
WebKitGTK cannot play audio files via the asset:// protocol (or at least
not reliably), returning MEDIA_ERR_SRC_NOT_SUPPORTED. Additionally,
convertFileSrc was double- encoding the path (/ became %2F).
Changed to read audio files directly using the fs plugin and create
blob URLs instead. Also added APPDATA to fs:scope permissions to allow
reading recordings from the app data directory.
* Fix audio playback on macOS by using asset protocol on non-Linux
The blob URL approach for audio playback works on Linux but breaks
macOS.
This reverts the blob change to use convertFileSrc with the asset
protocol on macOS/Windows while keeping the blob approach for Linux
where it's needed. Also adds proper cleanup of blob URLs to prevent
memory leaks when history entries are unmounted.
