Subject: [PATCH] fix: use D1 migrations instead of raw schema execution

- Create 0001_initial.sql with base schema (tables without interview fields)
- Keep 0002_interview_fields.sql for adding new columns
- Update deploy-worker.yml to use 'd1 migrations apply'
- Update justfile worker-migrate to use migrations

This fixes the 'no such column: lead_tier' error when deploying to
a production database that was created before interview fields were added.
