immichframe: set the admin password the new admin UI requires

immichFrame/ImmichFrame#698 added an admin UI that refuses to open
/admin unless IMMICHFRAME_ADMIN_PASSWORD is set, leaving users to edit
the unit by hand after an install or an upgrade from an older version.

Generate one, put it in the unit next to the other Environment lines,
and record it in ~/immichframe.creds the way the other scripts record
credentials. The update adds the line only when it is missing, so a
password already set by hand survives.
