fix: proper module resolution in all cases (Node CJS, Node ESM, bundler)

* Add extensions to all imports

* Set module resolution to `bundler` to avoid Node specific behavior

* Use `ts2mjs` to rename files to `mjs`

* Add extensions to `@bbob/types` imports

* Fix `package.json` for proper ESM extension and type separation

* More module resolution stuff change (`node16` for everything, `node` for Vue 2 plugin)

* Use `ts-jest-resolver` for `js` -> `ts` resolving in Jest

* Add changeset

* Add import extensions to frontend libs
