Every app with a generated admin password displayed "(not generated)" in its
Login Details. The credential matcher anchored on
^CFG_<APP>_(ADMIN_)?(PASSWORD)$, which stopped matching when generated keys were
given slot numbers — CFG_MATRIX_ADMIN_PASSWORD_1 and friends no longer hit the
regex, so the lookup fell through to its placeholder.
All ten apps carrying an admin password were affected: adguard, authelia,
bookstack, gitea, invidious, matrix, nextcloud, owncloud, pihole and stalwart.
Allow an optional _<n> tail. The anchor is kept otherwise, so a database or
upstream credential still cannot be mistaken for a login — CFG_<APP>_DB_PASSWORD_1
does not match, which is the case the anchor was added for.
