trpc-admin: migrate junit4 to junit5 and upgrade resteasy

[drow931]

Summary

Upgrade Jakarta EE dependencies from Jakarta EE 8 to Jakarta EE 10 to fix compatibility issues with RESTEasy 6.x.

Problem

When using RESTEasy 6.2.15.Final, the following runtime errors occurred:

• NoClassDefFoundError: jakarta/xml/bind/annotation/XmlElement
• NoClassDefFoundError: jakarta/activation/DataSource

These errors were caused by version mismatches between RESTEasy 6.x (which requires Jakarta EE 10) and the existing Jakarta EE 8 dependencies.

Changes

BOM (trpc-dependencies-bom/pom.xml)

• Upgrade jakarta.xml.bind-api.version: 2.3.2 → 4.0.2
• Upgrade jakarta.activation-api.version: 1.2.1 → 2.1.3
• Add angus-activation.version: 2.0.2 (Jakarta Activation implementation)

Admin Module (trpc-admin-default)

• Replace javax.ws.rs.Path with jakarta.ws.rs.Path
• Replace NettyJaxrsServer with UndertowJaxrsServer
• Add jakarta.activation-api and angus-activation dependencies

Testing

• Unit tests pass
• Admin service starts successfully without NoClassDefFoundError
