BCom intercom camera: improved config

- Invert locks: true is unlocked, false locked
- Merge SD capacity into attribute of SD status, SD Format status into
  attribute of SD Format button. These are not interesting enough to be
  sensor entities.
- handle empty string for doorbell idle state

Issue #2835
