Fix Playwright tests failing when run together

[jnioche]

The issue was that ProtocolTest and PageActionsLiveTest both extended AbstractProtocolTest and shared the same static Jetty server instance. When running tests together, the server would be stopped by one test class before the other could use it, causing ERR_CONNECTION_REFUSED errors.

This fix creates a new BasePlaywrightTest class specifically for the Playwright module that gives each test class its own isolated server instance.

Changes:

• Created BasePlaywrightTest with proper server management
• Updated ProtocolTest to extend BasePlaywrightTest
• Updated PageActionsLiveTest to extend BasePlaywrightTest
• Removed redundant getHandlers() overrides

Testing
• Ran full test suite: mvn test -pl external/playwright - PASS
• Ran individual tests: mvn test -pl external/playwright -Dtest=PageActionsLiveTest - PASS
• Ran individual tests: mvn test -pl external/playwright -Dtest=ProtocolTest - PASS

If you don't mind @jnioche , I finished your PR by reverting 90% of it. :)
The main issue was in the AbstractProtocolTest the AfterAll stopJetty() method stopped the jetty server, but the variable remained initialized after the first subclass test finished (E.g.: HttpProtocolProxyConcurrencyTest).
When the second subclass wanted to initialize the jetty as it was in the BeforeEach initJetty(), it checked the httpServer is already initialized (but it wasn't running) so skipped the reinitialization.

thanks @sigee

apologies for the half baked PR, I was evaluating Mistral's vibe tool and thought I would try it on a simple PR. Meant to have a closer look at it but you beat me to it.
