## What changed?
<!-- Describe what has changed in this PR -->
Linter to enforce import aliases for protobuf imports.
Enforced rules across entire codebase.
## Why?
<!-- Tell your future self why have you made these changes -->
Consistency. Relief reviewers from pointing it out.
We had 100+ violations.
## How did you test it?
<!-- How have you verified this change? Tested locally? Added a unit
test? Checked in staging env? -->
Running
```
make lint-code
.bin/golangci-lint-dafd65537336fdce063c492a7ab2a68cc89f8d52 run --config=.golangci.yml | grep importas
```
comes up empty (compared to say `grep typecheck`).
Plus compiler and tests ofc.
## Potential risks
<!-- Assuming the worst case, what can be broken when deploying this
change to production? -->
Me smuggling in an easter egg into the code (I didn't, I swear 🙃)
## Documentation
<!-- Have you made sure this change doesn't falsify anything currently
stated in `docs/`? If significant
new behavior is added, have you described that in `docs/`? -->
## Is hotfix candidate?
