feat: add production deploy script with auto-rollback and Gitea Actions workflow

Add automated production deployment pipeline:
- scripts/deploy-prod.sh: Full deployment script with pre/post DB backups,
  migration tracking via shared.schema_migrations table, health checks,
  and automatic rollback on failure (restores DB, reverts code, rebuilds)
- .gitea/workflows/deploy.yml: Manual-trigger Gitea Actions workflow for
  intentional production deployments with optional --seed-existing flag
- scripts/db-backup.sh: Add --yes/-y flag to skip interactive confirmation
  prompts, enabling automated restore during rollback

+# Production Deployment Workflow for HOA LedgerIQ
+#
+# Trigger: Manual only (workflow_dispatch) — production deploys are intentional.
+# Runner:  Self-hosted on the production server at /opt/hoa-ledgeriq.
+#
+# This workflow does NOT use actions/checkout. The runner operates directly
+# on the production directory. The deploy script itself handles git pull.
