CAMEL-23149: Add TLS configuration options to camel-iggy

[gnodet]

Summary

• Add tlsEnabled (boolean, default false) and tlsCertificatePath (String) configuration options to IggyConfiguration
• Update IggyClientFactory to apply TLS settings when building TCP and HTTP iggy clients via enableTls() and tlsCertificate(path) builder methods
• Propagate TLS parameters through IggyClientConnectionPool, IggyProducer, and IggyConsumer
• Add unit tests for TLS configuration defaults, setters, copy behavior, and endpoint URI parsing

Test plan

• Unit tests pass (IggyConfigurationTest with 5 tests covering defaults, setters, copy, and endpoint URI parsing)
• Integration tests with TLS-enabled Iggy server (requires TLS-configured Iggy instance)

I think we should expose SSLContextParameters as configuration. This is for PQC.

@oscerd Makes sense — SSLContextParameters would give full control over TLS configuration including PQC cipher suites. This could be a follow-up enhancement on top of the current basic TLS options. I'll note it for a future iteration.
