Also check Seerr parent permissions (#1631)

## Description
When saving Seerr permissions on the WebUI, if a "parent" permission is
checked, only its bit is flipped and its children's bits are not. So
clients must check if a user has the permission _or_ its parent.

For example, if just "Request 4K" is checked, the flags for "Request 4K
Movies" and "Request 4K TV" will not set explicitly.

### Related issues
Fixes #1630

### Testing
Emulator & unit tests, also manually reviewed API requests/responses on
Seerr's web UI

## Screenshots
