Rotate oikos-console-deploy webhook secret

The value written to apps' /etc/oikos-console-deploy/secret didn't
match what Gitea webhook 14 had configured, causing every deploy
attempt to 403 with a signature mismatch — likely drift introduced by
the earlier two-step PATCH sequence (secret set in one call,
branch_filter/active restored in a second call without re-including
the config object). Rotated cleanly this time: fresh secret set on
Gitea and re-encrypted here in one pass, single atomic PATCH covering
config+events+branch_filter+active together.
