Describe the bug
On version 2.12.1 (which I updated to yesterday), seem to rendered setting up any new Redirection Host broken.

No matter what domain I put in in "Domain Names" or in "Forward Domain". Kept getting the message "data/forward_scheme must be equal to one of the allowed values".

Nginx Proxy Manager Version
v2.12.1

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Redirection Hosts'
2. Click on 'Add Redirection Host'
3. Add any new "Domain Names" and "Forward Domain"
4. Error in red pops up - "data/forward_scheme must be equal to one of the allowed values"

Expected behavior
New Redirection Host get added without any errors.

Screenshots

Operating System
Hosted in Debian 12. Standard Docker install.

Additional context
Tried it on multiple NPM instances running 2.12.1. Ran on a NPM running version "v2.11.3" and it's working fine.

Start by reproducing the Redirection Hosts flow on version 2.12.1 with the Docker image, then compare it with the working 2.11.3 setup. Trace the validation that rejects forward_scheme and confirm that creating a Redirection Host succeeds for the reported domain and forward-domain inputs.
