Switch the OpenMAIC root and the in-house @maic/* SDK packages
(@maic/dsl, @maic/importer, @maic/renderer) from AGPL-3.0 to the MIT
License. Updates LICENSE files, package.json license fields, README
badges and license sections (EN/ZH), CONTRIBUTING, and renderer FONTS
note.

Third-party vendored packages are left untouched: packages/mathml2omml
remains LGPL-3.0, packages/pptxgenjs remains MIT.
