Add integration tests for transformation, header, filter, http, and log kamelets

[oscerd]

Summary

• Add 10 new Citrus integration tests covering actions, sources, and sinks:
  • Transformation actions (4): drop-field, mask-field, replace-field, hoist-field
  • Header actions (1): insert-header
  • Filter actions (2): predicate-filter, has-header-filter
  • Source kamelets (1): http-source
  • Sink kamelets (2): http-sink, log-sink
• Fix YAML folded block scalar (message: >) to quoted string in existing pipe definitions (extract-field, insert-field, data-type) to avoid trailing newline in property resolution
• Add 4 new @CitrusTestFactory methods to CommonIT.java for the new test categories (header, filter, httpTests, log)

Test plan

• Verify all new pipe definitions start correctly with Camel JBang
• Run CommonIT integration tests and verify new tests pass
• Verify existing tests (earthquake, timer) still pass
• Verify the YAML message property fix resolves property resolution for existing transformation tests
