Convert all 11 incident API routes from Supabase PostgREST to Drizzle
ORM with withUser/asAdmin/writeAuditLog patterns and RLS enforcement.
Only uploadEvidenceFile retains supabase client (Phase 5 storage work).

Custom auth stack: bcryptjs password hashing (cost 10, GoTrue-compatible),
jose JWT session cookies (edge-safe, 8hr TTL), new API routes for
login/logout/reset/change-password, middleware rewritten to JWT-only
verification with no DB access. All 38 protected pages and API routes
migrated from supabase.auth.getUser() to getSession(). Supabase .from()
queries retained for Phase 4. lib/db/index.ts refactored to lazy Proxy
singleton to avoid module-level throw during Next.js build.
tsc: clean, build: clean, tests: 4/4 passed
