fix(tylohelo_sl2_sauna): default conflicts with hidden

- other uses of hidden require that it is available only for forward
  mappings, but the way default is used requires reverse mapping also.
- remove the hidden tag in this config to allow the default mapping to
  work as intended.
- Avoid returning default mappings that are hidden and instead log an
  error to get them fixed quickly.
