feat(seed): ~5x richer demo data via deterministic generators
Rewrite scripts/seed-demo.ts as a thin orchestrator over a new scripts/seed/ module (rng, pools, helpers, content, schedule, logs, generators). Scales demo data from 6 users/3 projects to ~30 users/15 projects with ~5-8x per-table content (~6.8x total rows) via a seeded mulberry32 PRNG for full reproducibility (incl. bcrypt salts and file/URL identifiers). FK-safe ordering, real captured IDs for activity logs, enum pools typed against lib/types. Preserves canonical login credentials and projects.
