The first-run seeder only applies ADMIN_EMAIL/ADMIN_PASSWORD on an empty
database and then silently ignores them. People add the vars after the first
boot, or pull a fresh image without clearing ./data, restart, and cannot log
in with no hint why (#1339). The default is a generated password (not the
.env.example placeholder), printed once in the first-run box. Now: warn loudly
when the vars are set but a user already exists, and warn on a partial
(one-of-two) config instead of quietly falling back.
Also ship the reset-admin recovery script in the image -- it was never COPYed in
despite the wiki referencing it. node server/reset-admin.js resets/creates
admin@trek.local with a generated password (RESET_ADMIN_EMAIL/RESET_ADMIN_PASSWORD
overridable), picks a free username so it cannot trip UNIQUE(username), and sets
must_change_password.
