fix(exercise): persist completion policy and improve dev build workflow (#754)

* fix(exercise): persist completion policy and pass threshold on save

buildExerciseUpdateFields accepted completionPolicy and passThreshold in
the validation schema but never mapped them to the database update, so
exercise settings appeared to save while reverting on refresh.

* fix(db): build workspace deps before compiling

@cio/db imports @cio/utils/notifications, which only exists after
@cio/utils is built. Building db in isolation failed when utils dist
was missing or stale.

- Add a db prebuild step for question-types, utils, and email
- Clean dist and tsbuildinfo before utils and email builds so
  incremental tsc cannot skip emission after dist was removed

* chore(dev): build api workspace deps before api:dev

Run turbo build for @cio/api and @cio/jobs-worker dependencies before
starting the dev servers, so missing dist/ folders do not break startup.
