Follow-up to the Projekt-card change: the dev/release-control box must list its
actual update source (e.g. private Gitea) AND the public repo — the previous commit
showed only the source on dev. Replaced the single project link with projectLinks():
the public repo is always listed (validated slug, canonical fallback); the dev box
prepends its source when it is a real URL (a garbage/hostless source is dropped, never
an empty link). Staging/stable still list the public repo only — no private leak.
Codex review: no leak path on non-dev; hardened the dev source against a hostless URL.
Verified: 433 tests green (dev-both / non-dev-only / malformed-slug / garbage-source),
pint clean, /versions shows both links on the dev box with zero console errors.
