Describe the bug
No longer possible to use domain with port in Domain Name because of the error data/domain_names/0 must match pattern "^[^&| @!#%^();:/\\}{=+?<>,~'"]+$`

Nginx Proxy Manager Version
v2.12.3

Expected behavior
It had been working flawlessly for years until one of the recent updates disrupted my configuration

Screenshots

Operating System
Docker

Additional context
This change is completely incomprehensible to me. I had 15 services configured on one subdomain with different ports, e.g., sub.domain.com:5380, sub.domain.com:3001, etc., and they all stopped working after one of the recent updates (to be precise, I lost the ability to edit them via the GUI). Who was bothered by this port? Why force users into a single approach using the default 80/443 ports and differentiating services by domain?

Start by reproducing the GUI edit failure using the v2.12.3 Docker image and a proxy host such as sub.domain.com:5380. Trace the domain-name validation that produces the reported pattern error, then verify that existing domain-and-port configurations can be edited successfully without breaking the validation rules.
