Entity UI's: Investigate components that need updates/rewriting (continued)

**In #16052, a lot of investigation and fixes were done (and merged) to determine what else needs to be done. But that ticket became blocked on its dependency on sbc-common-components and bcrs-shared-components. I decided to "complete" 16052 and carry over that work into THIS ticket, once those dependencies are resolved.**

---

The upgrade to Vue3 will require work, including:
- updated package dependencies
- upgrade to Vuetify (with some components incompatible or missing)
- missing some packages (like `vue-property-decorator`)

This ticket is to research / try / identify / report what changes are needed for 1 or all 3 Entity UIs.

**Possible alternative:**

Instead of upgrading/converting the existing code to Vue3, we could start from a template project (aka boilerplate/scaffold) and move our code over. This is very likely more work, but may result in a cleaner configuration.

1. [Boilerplace Vue 3 + TS + Vite + Pinia](https://github.com/Lucas98Fernando/vue3-vite-ts-pinia-boilerplate)
2. [Getting started with Vue 3 + Pinia Store + Typescript...](https://dev.to/carlomigueldy/getting-started-with-vue-3-pinia-store-typescript-by-building-a-grocery-list-app-19km)

Start by reviewing the listed upgrade references and the remaining checklist, then inspect componentsCompanyInfo.ts, countries-provinces-mixin.ts, vuetify.ts, and the locally copied shared components. The work is complete only when the required Vue 3, Vuetify, dependency, styling, and unit-test changes have been identified and reported, but the issue does not define a bounded implementation scope.
