npeter83 2ef22982bb feat(plex): grouped collapsible playlist view + drag-and-drop + bulk add
Playlist view now groups a run of episodes from the same show into a
collapsible season/show block so a whole series doesn't sprawl into an
endless flat list; movies stay standalone (larger poster card in the
accordion). Two per-account layouts — Accordion and Tree — persisted via
LS.plexPlaylistLayout; show groups start collapsed. Reorder is drag &
drop (@dnd-kit): a show block moves as one unit, episodes reorder within
their show, keyboard-draggable via KeyboardSensor. Remove works per item,
per season, or per whole show. The add-to-playlist dialog is generalised
to a single leaf or a whole group (tri-state none/some/all with an in/size
count); the show page gains add buttons for an episode, a season, and the
whole show. i18n en/hu/de.
