fix: trust all directory owners in sandbox git commands

Sandbox setup runs git commands against project_dir which may be owned
by a different OS user, triggering git's 'dubious ownership' error.
Fix by passing -c safe.directory=* on all git commands that touch
project directories. Also add wildcard to global config for immediate
effect on the running server.
