case-create: surface Gitea repo result + UI retry button

The auto-creation in case_create had two failure modes that combined to
make repos silently missing: a stale GITEA_TOKEN returning 401, and the
outer try/except in case_create that swallowed every exception with a
bare pass. Result: cases like 8174-24 ended up with a local git repo and
Paperclip project but no Gitea repo, with no signal anywhere.

_setup_gitea_remote now returns {ok, url, error} and never raises; the
result is attached to the case JSON and the FastAPI endpoint logs a
warning when ok=false. The UI gets a "צור ריפו ב-Gitea" button on the
case header that appears only when the repo or remote is missing.
