Allow localhost HTTP URLs for the capport API
Allowing the capport API to be hosted on localhost makes it easy to
write fast, stable tests for the feature.
This was not possible because:
- Pre-validation of the URL used Patterns.WEB_URL, which is
over-restrictive and excludes domain names without TLD
- NetworkMonitor needs the API to be hosted via HTTPS which is working
as intended, however relaxing this requirement only for localhost
(for testing) seems reasonable.
