Fix OTP modal backdrop opacity for Tailwind v4

[Copilot]

The OTP modal backdrop was rendering as solid black instead of semi-transparent after the Tailwind v4 migration. The bg-opacity-* utility classes were removed in v4.

Changes

• Updated otp-modal.jte to use v4 color opacity syntax

- <div class="fixed inset-0 bg-black bg-opacity-50 flex items-center justify-center z-50">
+ <div class="fixed inset-0 bg-black/50 flex items-center justify-center z-50">

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• maven.vaadin.com
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java -classpath /home/REDACTED/.m2/wrapper/dists/apache-maven-3.9.9/3477a4f1/boot/plexus-classworlds-2.8.0.jar -Dclassworlds.conf=/home/REDACTED/.m2/wrapper/dists/apache-maven-3.9.9/3477a4f1/bin/m2.conf -Dmaven.home=/home/REDACTED/.m2/wrapper/dists/apache-maven-3.9.9/3477a4f1 -Dlibrary.jansi.path=/home/REDACTED/.m2/wrapper/dists/apache-maven-3.9.9/3477a4f1/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/vms/vms/web-backend org.codehaus.plexus.classworlds.launcher.Launcher compile -DskipTests (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
