feat(web): icon-only controls and readouts (#230)

Trash replaces the remove labels on title pages and season and
episode rows, a magnifier replaces the deck control, the season
on-disk readout carries a drive glyph before its 0/10, and the
TMDB, TVDB, IMDb and Rotten Tomatoes links carry drawn marks
shipped inline (wordmark badges plus a tomato), never remote
images. Every icon-only control keeps an aria-label naming the
action and the row or title it acts on, and the arm-then-confirm
delete speaks a visible amber "confirm" while armed, so the first
hit never destroys.

Shared CSS lives in one block in style.css headed
"icon-only controls (#230)" — .icon, .control-icon, .icon-mark —
for #231 to consume for the settings rows.
