Updated: improve URL regex pattern recognition and added test cases

[Miexil]

What does this PR do?

Updated URL regex to handle more cases, they can be checked in the updated tests.
The initial goal was to handle at least :

Should pass the regex:
https://www.anext.com.sg/ (ie, .co.uk format with https & www)
https://www.anext.com.sg/
mabanque.bnpparibas

Should not pass:
www
www.upfluence

Note

Strengthens URL validation and significantly expands test coverage.

• Replaces the old single regex with a composed URL_REGEX that supports optional protocol, www/non-www domains, multi-level TLDs (e.g., .co.uk), paths, queries, and fragments, while excluding IPs, localhost, ports, and non-http(s) schemes
• Updates unit tests to include extensive valid/invalid cases covering subdomains, mixed case, long paths, file extensions, anchors, and malicious/unsupported patterns
