feat: add database seed script and utility scripts

- src/db/seed.ts: comprehensive seed data with idempotent upserts
  - 5 users (system, gjermund, operator, technician, analyst)
  - 5 queues (Support Desk, Operations, IT Infrastructure, Facilities, Field Ops)
  - 1 lifecycle (Demo service lifecycle with new→open→in_progress→resolved→closed)
  - 5 custom fields (impact, location, channel, urgency, outcome) with short keys
  - 10 realistic support tickets with varied statuses, custom fields, and history
  - 3 scrips (OnCreate email, OnResolve custom field, customer notification)
  - 2 templates (auto-response, resolve notification)
  - --reset flag to truncate all data before seeding
- scripts/smoke-test.ts: API smoke tests
- scripts/watch-frontend.sh: frontend dev helper
