test: Jest configuration normalized

[tassoevan]

Proposed changes (including videos or screenshots)

It normalizes the Jest configuration over the monorepo.

This pull request modernizes and standardizes Jest configuration across multiple packages by converting CommonJS Jest config files to TypeScript modules, removing deprecated or unnecessary Jest options, and updating TypeScript configuration files to exclude Jest config files from builds. These changes improve type safety, maintainability, and build hygiene.

Jest configuration modernization:

• Converted Jest config files from CommonJS (.js) to TypeScript (.ts) modules in css-in-js, emitter, layout, and logo packages, using export default and satisfies Config for type safety. [1] [2] [3] [4]
• Removed the deprecated or unnecessary errorOnDeprecated: true option from Jest configs in several packages. [1] [2] [3] [4] [5] [6] [7]

TypeScript build configuration improvements:

• Updated tsconfig.build.json, tsconfig.cjs.json, and tsconfig.esm.json files across multiple packages to exclude Jest config files (e.g., jest.config.*) from builds, preventing them from being included in output. [1] [2] [3] [4] [5] [6] [7] [8] [9]

General cleanup:

• Ensured consistent use of testMatch and other Jest options across packages for better maintainability. [1] [2] [3] [4] [5] [6] [7]
