Enhance Codecov integration (#1136)

* Define sub-projects and set coverage threshold for failure in the `codecov.yml`; make both test execution engines to generate also JUnit reports; upload these JUnit reports to Codecov for analysis

* Fix UI Vite config and add more details to the API is-generated-code script

* Add API JUnit report file to `.gitignore`

* Fix the copy issue by mounting the volume

* put the exact report name to the `docker cp` command

* Added `set -euxo pipeline` to the `test_api_coverage.sh` script; try to fix the missing report issue by setting immutable flag and report directoty

* Revert `chattr` and `set` commands, as they cause errors

* debug

* put the filename of the JUnit report to upload

* `set -euxo pipefail` in `scripts/test_api_coverage.sh`
