chore: refactor @src imports

The webpack configuration used to include a weird line, that allowed all
non-implicit imports from src/. Such imports were ambiguous, and
required modification of the resolve path, which is unconventional.

To resolve this, we adopt the same solution as frontend-app-learning:
src/ imports are written as `from '@src/...'`.
