Merge master: Groq, and cleanup on a subscription

Three of master's changes land on the same lines as this branch, so most of
this is picking the newer shape and putting the local half back into it.

cleanup.py arrived while this was being written and is the right place for
a fourth provider, so the Target refactor of api.cleanup goes away: llama.cpp
becomes a name in cleanup.PROVIDERS next to OpenRouter, Claude Code and
Codex, and worker.py, meeting.py and filetranscribe.py go back to master's.

The settings window keeps master's one row per provider, hidden with
setRowVisible, rather than the two wrapper widgets this branch had. So does
speech to text, which was doing the same thing its own way.

The transcriber table has no room for a provider with no key and no base
URL, so the local one is answered before the lookup rather than added to
it, and an unknown name now falls back to openai by name: the shipped
default is no longer a key of that table.

The minutes stay on OpenRouter, which master already decided by routing
only the transcript through cleanup.run, so meeting_provider goes.
