Fix #7209: Handle trailing dot in FQDN URLs to prevent redirect loop

[MuraveyApp]

Summary

• Fixes infinite redirect loop when requesting FQDN URLs with trailing dot (e.g. https://pyropus.ca./)
• URL normalization now strips trailing dot before redirect comparison

Test plan

• Verify requests.get("https://pyropus.ca./") no longer raises TooManyRedirects
• Existing test suite passes
