Restore proper license headers for third-party bundled source code

[bobbai00]

Task Summary

When ASF license headers were added to the codebase (commit 832a2dd95), several third-party source files were incorrectly marked with Apache License 2.0 headers, when they are actually MIT-licensed code from external projects. This is a license compliance issue that needs to be addressed.

Source Project	License	Files Affected
TypeFox monaco-languageclient	MIT	pyright-language-service/src/main.ts, language-server-runner.ts, server-commons.ts
mbknor-jackson-jsonschema	MIT	common/workflow-operator/src/main/scala/com/kjetland/jackson/jsonSchema/** (13 files)
Google Angular	MIT	frontend/src/app/common/formly/array.type.ts

Required Actions

1. Restore original MIT license headers in the affected third-party files
2. Update the LICENSE file with proper THIRD-PARTY DEPENDENCIES section including:
   • List of bundled third-party files
   • Full MIT license text for each dependency
   • Copyright attribution to original authors
3. Update .licenserc.yaml to exclude third-party files from Apache header checking
4. Add sbt-license-report plugin for automated dependency license tracking
