chore(mobile): point Source-code link to self-hosted Forgejo (git.goon-foss.org)

GitHub goon-foss/goon stays soft-banned (whole namespace 404, 10 days after the
appeal, no response — flag abuse on the resolve-stream language, not DMCA). Migrated
the repo to a self-hosted Forgejo on our own VPS: zero ban risk, full control, and it
fits the project's self-hosted ethos. Settings → Source code now opens
git.goon-foss.org/goon-foss/goon.
