chore: improve lint setup

- update eslint config
- merged eslint rules for JS and TS to avoid duplicates
- extended stricter lint ruleset from typescript-eslint
- corrected wrong setup for certain eslint rulesets
- opt in to reportUnusedDisableDirectives config option
- fix or disable a lot of lint issues throughout codebase
- remove trailingComma: all from prettier config which is default in prettier v3
- add volta configuration to package.json to autoload correct node and pnpm versions
- upgrade all eslint and prettier related dependencies to latest
- remove config options from settings.json which are default anyways
- remove config options from settings.json which are outdated/unknown
- set up prettier as default formatter in settings.json
