fix(symphony): use token-embedded clone URL and increase hook timeout

The after_create hook was timing out because HTTPS clone required
interactive auth. Use token-embedded URL with $GITEA_TOKEN expansion
and increase hook timeout from 60s to 120s. Also add git push to
after_run hook so agent work is pushed back to Gitea.
