refactor: CSS task 11 — audit and remove 22 unused tokens

Removed: --accent-underline, --accent-hover-underline, --font-prose,
--grid-gap-tight, --scrollbar-size, --width-full, --absolute-white,
--task-done/wip/blocked/todo, --callout-info/warn/error/note,
--session-bg, --wikilink, --redacted, --syntax-function/number/operator/tag

168 → 146 defined tokens. Build passes.
