fix(a11y): drop redundant alts and the landing em dash

Replace generic alt="Avatar" / alt="Character" with empty alts on
images that visually duplicate a name already present as adjacent text
(Wrapped activity avatar, Hololive stream icon, three Birthdays
covers); screen readers stop announcing "Avatar" / "Character" twice.
Also swap the em dash in the landing subheadline for a comma per the
project copy rule.
