Fix project build

[selutin99]

Summary

• Update qulice-maven-plugin to 0.24.0
• Fix violations of new/strict qulice checks
• Fix markdown-lint errors

Why

• The goal is to bring back the green build and ensure compliance with current qulice & markdown-lint requirements

Notes

• The changes do not affect the business logic, only the style/formatting
• Qulice 0.22.0 no longer works correctly with SPDX licenses declared in project files, therefore the plugin version had to be upgraded to 0.24.0. Fixed violation example: Checkstyle: src/.../*.java[2]: Line does not match expected header line of ' * The MIT License (MIT)'. (HeaderCheck)

@yegor256, could you please restart the job with the maven build for ubuntu-24.04? It seems to have stuck while completing the tests

@selutin99 just push something to branch, it will restart - it's usually easier than waiting for project architect (me) :)

No problem, thanks for the suggestion!
I just didn’t want to restart the whole build unnecessarily and consume organization github actions limits for another full run. I’ll push an empty commit to trigger build

@selutin99 thanks!
