CAMEL-23431: Migrate thrift tests from AvailablePortFinder to port-0 binding

[gnodet]

CAMEL-23431

Summary

Third PR for CAMEL-23431. Migrates all camel-thrift tests (10 test files) from AvailablePortFinder to port-0 binding, completely eliminating AvailablePortFinder from the thrift module.

Production code:

• Add getLocalPort() to ThriftConsumer to expose the OS-assigned port after server start

Producer tests (create own server):

• ThriftProducerBaseTest: Move server creation to doPreSetup(), bind TNonblockingServerSocket to port 0
• ThriftProducerSecurityTest: Same pattern with TSSLTransportFactory
• ThriftProducerZlibCompressionTest: Same pattern with TServerSocket
• ThriftThreadPoolServerTest: Bind to port 0 in @BeforeEach

Consumer tests (Camel component creates server):

• All 5 consumer tests use port 0 in from() URI, then read back actual port from ThriftConsumer.getLocalPort() for client connections
• ThriftConsumerConcurrentTest: 2 ports (sync + async) both use port 0

Test plan

• mvn test in camel-thrift — 39 tests pass
• CI green
