This change updates the `validate_webhook_url` function to strictly enforce the use of `https://` for Discord webhook URLs. This prevents the accidental transmission of sensitive webhook tokens over unencrypted HTTP connections.
Security Impact:
- Prevents potential Man-in-the-Middle (MitM) attacks from capturing webhook tokens if a user inadvertently copies an `http://` URL (e.g. from a proxy or non-standard source).
- Aligns with Discord's API security best practices.
Changes:
- Updated `WEBHOOK_URL_PATTERNS` regex to require `https`.
- Updated `validate_webhook_url` logic to check for `https://` prefix.
- Added unit test `test_http_url_rejected` to verify the fix.
