Deploy ABC beta from Development instead of master (#37)

## Summary
- A no-ref beta deploy of `abc_be`, `abc_worker`, and `abc_fe` checks out `Development` instead of `master`.
- `livekit` and every other app still use their current default branch.
- CI that passes `--ref` is unchanged; this only affects the catalog fallback.

## Test plan
- [ ] `scripts/deploy.sh --app abc_be --env beta` resolves ref `Development`
- [ ] Same for `abc_worker` and `abc_fe`
- [ ] `livekit` still resolves `master`
