feat(player): persistent auto-advance + loop playback modes

Two saved-to-account playback settings on the player's prev/next bar (any queued
player — feed or playlist): Auto-advance (Off/Next/Prev/Random — what plays when a
video ends) and Loop (Off / One = repeat the current video / All = wrap the list
at its ends; a single-item list repeats). Stored in users.preferences
(playerAutoAdvance/playerLoop), read from the cached me + written via savePrefs so
they apply everywhere and survive reloads.

The feed's player queue is now the live filtered feed with the watch-state filter
NOT applied — marking the current video watched keeps it in the sequence (no
reindex/reload mid-play), while a hidden video still drops out. Removes the old
frozen-queue workaround and the boolean autoAdvance prop. i18n en/hu/de.
