chore: setup twenty-ui absolute path alias (#4732)

Split from https://github.com/twentyhq/twenty/pull/4518

- Setup `@ui/*` as an internal alias to reference `twenty-ui/src`.
- Configures twenty-front to understand the `@ui/*` alias on development
mode, so twenty-ui can be hot reloaded.
- When building on production mode, twenty-front needs twenty-ui to be
built beforehand (which is automatic with the `dependsOn` option).
- Configures twenty-front to understand the `@ui/*` alias when launching
tests, so there is no need to re-build twenty-ui for tests.
