chore: update dependencies and adjust ESLint rules

- Updated dependencies in package.json:
  - "@eslint/js" from "^9.14.0" to "^9.25.1"
  - "@types/eslint__js" from "^8.42.3" to "^9.14.0"
  - "eslint-config-prettier" from "^9.1.0" to "^10.1.2"
  - "eslint-plugin-sonarjs" from "^2.0.4" to "^3.0.2"
  - "typescript-eslint" from "^8.13.0" to "^8.31.1"

- Modified ESLint rules in rules-snapshot.json:
  - Changed "no-unused-vars" from [2] to [0]
  - Added and adjusted various SonarJS and TypeScript ESLint rules, enabling or disabling them as necessary
