International phone numbers rejected during registration (UK numbers blocked)

[13fingerfx]

Describe the bug, issue, or problem:
The registration form appears to reject non-US phone numbers despite the service stating it is available worldwide.

I am attempting to register from the United Kingdom with country set to United Kingdom (GB).

The phone field validation appears hardcoded to US/NANP formatting only.

Attempted formats:

+447801076821
447801076821
+44 7801076821

All fail validation.

The exact error shown is:

Phone number must be in the format +1-8559805959 and contain at least 4 digits

This prevents account creation for international users.

Steps to reproduce:

Open the registration page
Select United Kingdom (GB) as country
Enter a valid UK mobile number
Attempt to register

URL (if applicable):
https://dash.domain.digitalplat.org/auth/register

Domain Name (if applicable):
N/A

Expected Behavior:
The registration form should accept valid international phone numbers, especially when non-US countries are selected.

Examples that should work:

+447801076821
Other valid E.164 international formats
