Check for protocol and port in allowances

### Feature description

Currently allowances only consider the domain they are being created on regardless of the protocol or port being used.

### Describe the solution

- Include the fully qualified origin for allowances (maybe `origin.domain` could be used here instead of `origin.host`)
- Migrate existing allowances (prefix with https)
- Potentially display a warning on the enable screen when connecting to non-ssl domains (MITM)
