[TEST] Add component tests for TimedConnection.js (Java WebSocket Template)

Description
Adds unit tests for the `TimedConnection.js` component in the Java Quarkus WebSocket client template. The component contains complex conditional logic but currently has no component-level test coverage.

Component location
`packages/templates/clients/websocket/java/quarkus/components/TimedConnection.js`

I’m happy to submit a PR implementing this.
