## Motivations:
- less workflow to whitelist as blocking for PRs
- less if condition per step

cons:
- quite verbose
- need to manually sync the `ci-NAME-status-check` needs list to any
other existing and should be dep jobs

## Version migration
Migrated to the latest `changed-files@45` version, getting rid of the
`set-output` usage warnings

## Tests runs:

With mutation:
- [Success
flow](https://github.com/twentyhq/twenty/actions/runs/12791958651/job/35661546343)
- [server-setup failure
flow](https://github.com/twentyhq/twenty/actions/runs/12792225779)
- [Other job failure
flow](https://github.com/twentyhq/twenty/actions/runs/12792313463), one
of the `inner` job failed
- [Manual cancel
flow](https://github.com/twentyhq/twenty/actions/runs/12792313463)
`ci-server-status-check` also has the `cancelled` status
- [Matrix
failure](https://github.com/twentyhq/twenty/actions/runs/12806883553)

Without mutation:
- [Nothing to do
flow](https://github.com/twentyhq/twenty/actions/runs/12792098384),
skipped `inner` job but `ci-server-status-check` still succeeded

## Notes
### Linter
We should setup a `yml` prettier and linter for the `.github/worfklows`
folder
### Centralized `ci-NAME-status-check` logic
Unfortunately I couldn't achieve to either make a `composite` action or
a `reusable-workflow`, as I could not access the correct layer to run
the `always` but also acessing the `needs` context
