Make the episode screen the player and delete the separate player screen

Opening an episode now puts you in its transport at the stored position;
pressing play changes nothing about the layout. One primary control
(Play/Resume/Pause) with back/forward, a speed chip that opens the four
offered speeds (stored 1.5/1.75 still play and are named on the chip),
and everything secondary behind a top-bar overflow: queue, download,
played, watch, mark-older, chapters, and the publisher-copy action
(behind a dialog carrying its warning). Description shows about two
lines, the rest on tap.

The now-playing bar, library bar, queue, share receiver and nav graph
all open the playing episode's screen. PlayerViewModel stays the single
owner of playback state; no playback decision moved into the UI.

PlayerScreen.kt and WatchButton.kt are deleted. Coverage drop, if any,
is from removing covered dead code.
