fix: strip playback accelerators whenever any text input is focused (#2059)

The command-palette-specific IPC approach didn't cover other modals
with inputs (settings search, playlist creation, etc.). Replace it
with document-level focusin/focusout listeners that signal the main
process whenever any input/textarea/contenteditable gains or loses
focus, so the menu rebuild is triggered automatically for all current
and future input surfaces.
