stop caching transcriptions and OCR

Both endpoints kept a copy under cache/ and returned it on the next call, and
also short-circuited when the sibling .md already existed. So a re-run never
re-ran: a bad transcription stayed bad, and there was no way to ask for a fresh
one. Every caller passes saveNextTo, so the cache-path return was dead code
anyway.

Both now always do the work and overwrite the sibling. CACHE_PREFIXES drops the
two prefixes, since /save-result has nothing left to promote for them; the tts
and audio caches are untouched.

Also fixes the task runner output being unreadable in light mode. The panel is a
fixed dark terminal, but stdout lines were classed text-foreground, which follows
the app theme and renders black on the dark background. They now inherit the
pre's own colour.
