feat(legacy): disable public radio page and redirect to login (#2903)

### Description

Many people don't need the public page and use libretime purely for
playout management. This adds the ability to have libretime publicly
available but only present the login page to the user.

**I have updated the documentation to reflect these changes**:

no, but i will add documentation if this PR is accepted.

### Testing Notes

**What I did:**

Toggle the new ceckbox on the general settings, log out and back in and
check behaviour.

note: this may have conflicts with the trim overbooked PR since the
toggle sits in the same place. If both are accepted this needs to be
formatted nicely :-)
