chore(eslint-config): upgrade config to use ESLint v9 & FlatConfig

[grixu]

• Migration to ESLint v9 and adoption of FlatConfig for a more modern and flexible configuration approach.
• Each module (ecma, typescript, nextjs, playwright, style, architecture) is a factory for ESLint configurations, which can be used individually or together in projects.
• Enhanced support for ECMAScript, TypeScript, Next.js, Playwright, and architectural rules.
• Integration of Prettier and Perfectionist plugins for improved code formatting and consistency.
• Updated rules and settings to align with the latest best practices and standards.
• Improved handling of import/export rules and JSON file sorting.
• Removal of deprecated and non-compliant plugins.

I've added the resolutions field to the root package.json to allow local linting in this repo, due to its using the ESLint v8 and Prettier v2. The package itself is linted & formatted using itself.

I think you meant ESLint v8, right?
