Multi-user authorization hardening from a full security evaluation (EVALUATION.md):
- P0: /api/settings/{export,import}-db are now admin-only. Previously any signed-in user could download the whole instance DB (all bcrypt hashes + plaintext AI keys) or replace it wholesale. Per-user CSV export/import stays open.
- AI custom-URL providers (Ollama, OpenAI-compatible) are now admin-only, and every server fetch to a user-supplied URL passes through assertSafeProviderUrl (blocks link-local/cloud-metadata; private LAN allowed by design). Fixed-URL cloud providers stay per-user. Removed the dead legacy /api/ai/config route.
- Dev: fixed broken quick-start (added npm run create-admin; rewrote README; dropped dead CLAUDE_API_KEY) and the export-db 0-byte path resolution (resolveDatabasePath now matches Prisma).
ExVer bumped to 1.1.0:8 (no schema/data migration). Tests 197 pass, build green, tsc clean.
