Merge branch 'main' into feat/demo-otp-autofill

The theme was inline text in a Helm template. It now lives next to the realms
and is seeded as rr-kc-theme by seed-configmaps.sh, like every other file
input, so it can be edited as a normal Keycloak theme. demo.otpAutofill now
only decides whether KC_SPI_THEME_DEFAULT is set (big.env skips values that
render empty); off, Keycloak keeps its stock theme.
