chore: switch web to port 9000 (test.04080616.xyz) + exclude test files from bot tsc build

- Local dev WEB_PORT now 9000 to match the planned dev/staging domain
  test.04080616.xyz. Production deployment uses port 8100 mapped to
  rexwa.04080616.xyz (configured in plan 4).
- apps/bot/tsconfig.json: exclude src/**/*.test.ts from the production
  build (vitest types only present at dev time, mirrors the same fix we
  made earlier for packages/shared).
