fix(player): drop "Tap for sound" pill — speaker toggle is enough

User feedback (2026-06-07, report 4bdca61e) on the prior mute change: the always-
visible "Tap for sound" pill is redundant — the 🔇/🔊 toggle in the top controls
is enough. Removed the pill (+ its styles); video still starts muted and the
speaker toggle unmutes.
