feat(plex): player HTPC polish — Stop button, keyboard help, time-remaining + clock, scroll-restore
- Explicit Stop button (stops playback + returns to the library). - Keyboard cheat-sheet overlay toggled with 'H' (movie hides the episode-nav row). - Backspace = stop & back to feed (HTPC-remote convention); closes the help first. - Time-remaining readout beside the seek bar + a live wall clock in the top bar (both fade with the controls). - PlexBrowse restores the grid scroll position when returning from the player, so Back lands on the same card instead of the top of the library. - New plex.player i18n keys (stop/help/keys.*) in en/hu/de.
