app/: production port — Postgres + Prisma + OTM-account auth (v0.2.0)

Prototype stays untouched (Bonna's laptop daily driver until cutover).
app/ is the deployable bms-backbone: same routes/frontend, Prisma models
replacing node:sqlite, session-cookie login backed by a User table seeded
via the platform SEED_OWNER_* convention (bcryptjs), /api/health with
APP_VERSION, photos/files under DATA_DIR (/app/data uploads mount),
Dockerfile + entrypoint (prisma db push + owner seed + serve), and a
one-shot sqlite→postgres migration script for Bonna's existing data.
