ui(tokens): migrate text-[10px] to text-xs across 23 components
Replace all arbitrary text-[10px] / text-[9px] with the standard Tailwind
text-xs token. Also migrates nearby arbitrary width values where applicable
(max-w-[200px] → max-w-48, max-w-[120px] → max-w-32, h-[1px] → h-px).
Only documented exceptions remain: avatar xs (text-[10px] for w-6 h-6
initials) and badge JSDoc reference.
Affected areas: admin views, marketplace, player, settings, chat, upload,
education, commerce, library, PWA, search, navbar, user card.
