refactor: more lint improvements

- set parserOptions.ecmaVersion to latest and env to es2024 in eslint config
- install missing types libraries
- install eslint-plugin-sonar
- enable eslint-plugin-sonar recommended rules and declare jsx-runtime for react in eslint config
- clean up disabled lint rules which don't inflict problems anymore
- disable various lint issues and fix others
