Add Post-Quantum Cryptography (PQC) hybrid approach test coverage for HTTP component

Implements hybrid RSA+ML-DSA certificate validation for HTTP component using BouncyCastle JSSE
provider. Adds new pqc-certificate-generator test support module for generating hybrid certificates
following BC Almanac Chimera pattern (page 6).

Key changes:

• New test infrastructure: integration-tests-support/pqc-certificate-generator module
• Hybrid certificate generation using NIST-standardized ML-DSA algorithms (FIPS 204)
• HTTP integration test with nginx serving hybrid certificates
• Custom HybridCertificateTrustManager validating both RSA and ML-DSA signatures
• Standard TLS 1.3 handshake with application-level PQC validation

Technical approach:

• Uses standard TLS with hybrid X.509 certificates (RSA + ML-DSA keys via extensions)
• Compatible with any TLS 1.3 server (no OQS/protocol modifications needed)
• Client-side validation via @PQCCertificates JUnit extension

@JiriOndrusek You can probably rebase on main to get this merged.

[JiriOndrusek]

I'm going to do that, probably will check the code as well, to align with the new example added in apache/camel-quarkus-examples#494

[JiriOndrusek]

I rebased the PR and refactred it to be compliant with pqc-http example.
But there are possible more simplifications of the example after this Pr is merged. i reported them as #8550
