Dashboard webhook URL validation rejects valid URLs without a TLD

[digitalby]

Description

The webhook configuration page in the RevenueCat dashboard rejects URLs that don't include a top-level domain, showing:

Please enter a URL that starts with "https://" and includes a host and top-level domain.

This prevents using valid HTTPS URLs like https://myhost.ts.net:3000/webhook or IP-based URLs like https://100.68.18.78:3000/webhook, which are common in self-hosted and Tailscale setups.

Expected behavior

Any valid HTTPS URL should be accepted. The webhook delivery infrastructure doesn't need a TLD to issue an HTTP request. The current validation appears to be an overly strict client-side regex rather than a hard backend requirement.

Steps to reproduce

1. Go to Project Settings > Integrations > Webhooks
2. Enter a valid HTTPS URL that uses an IP address or a hostname without a traditional TLD (e.g. .ts.net, .local, or an IP)
3. Observe the validation error

Context

Filing here since there's no dedicated repo for dashboard issues. Happy to move this if there's a better place.
