* test(web): drop enzyme in favor of react-testing-library
Enzyme is falling behind in maintenance, it is currently maintained by one primary developer and still does [not support React 17](https://github.com/enzymejs/enzyme/pull/2430) despite it being released in October 2020.
[react-testing-library (RTL)](https://testing-library.com/docs) is [recommended by Facebook](https://reactjs.org/docs/test-utils.html#overview) and encourages writing tests that avoid testing implementation details.
* build(deps): update react monorepo to v17 (major)
* build(deps): remove @types/{enzyme,jest}
* refactor(web): use absolute imports with aliases
Refactors all of the TS/JS frontend to utilise absolute imports along with import aliases.
Each of the paths within `src` are represented with their own alias:
* @assets
* @components
* @constants (new)
* @hooks
* @layouts
* @models
* @services
* @themes
* @utils
* @views
`Routes.ts` and `constant.ts` have been relocated to the constants directory for consistency.
