Adds a "Load subtitle from file…" row to the Subtitles section on iOS (document picker) and macOS (open panel), available when playing files from local folder, SMB, or WebDAV sources. The picked file is copied into the per-video temp subtitle directory, registered as a selectable Caption (displayed by filename), and activated through the existing loadCaption flow. The Subtitles tab and captions control button now also appear for media-source files without any subtitles.
