ECSoC_2026: Improve URL scanner input normalization and validation

[Babin123456]

Problem

The URL scanner only prepends https:// and relies mostly on backend errors for invalid input.

Current Behavior

Unsupported schemes and incomplete domains can lead to vague or delayed scan failures.

Why This Improvement Is Needed

Users should receive immediate, actionable feedback before a network request is made.

Proposed Solution

Add client-side URL normalization that accepts domains, blocks unsupported schemes, validates complete hostnames, and returns clear error messages.

Expected Outcome

Scanner input becomes more reliable and user-friendly while keeping backend validation intact.

Additional Notes

Backend validation remains the source of truth.

Hi team! I'd love to implement the client-side URL normalization to block unsupported schemes and validate hostnames before making network requests. Could you please assign this issue to me?

Also, is this issue under the ECSoC program? If it is, could an admin please add the "EcSoc26" label to it? Thanks!
