Refactor to Vue 3 recommended ESLint rules

These updates ensure better adherence to Vue 3 standards and improve
overall code quality and readability.

- Update ESLint configuration from Vue 2.x to Vue 3 rules.
- Switch from "essential" to strictest "recommended" ESLint ruleset.
- Adjust ESLint script to treat warnings as errors by using
  `--max-warnings=0` flag. This enforces stricter code quality controls
  provided by Vue 3 rules.
