security: close audit findings #19–#23 and harden Docker setup (#24)

#19 MFA QR code: render locally via qrcode package, remove external qrserver.com request
#20 Webhook SSRF: add ssrf-guard.ts with DNS-verified IP blocklist; enforce on create/update/test/dispatch
#21 /api/perf: fail-closed when CRON_SECRET missing; remove query-string token auth
#22 CSP: remove unsafe-eval and unsafe-inline from script-src in production builds
#23 Active session registry: forward jti into session object; validate against ActiveSession on every tRPC request

#24 Docker: add missing packages/application to Dockerfile.dev; fix pnpm-lock.yaml glob;
    run db:migrate:deploy on container start so a fresh checkout boots without manual steps

Also: fix pre-existing TS error in e2e/allocations.spec.ts (args.length literal type overlap)
