Empty initrd for display, add rp1_dsi module

ALL RP1 hardware (gpio, clocks, dsi) sits behind the RP1 PCIe
southbridge, which isn't ready until ~12s. Loading any display
module in initrd (~3s) crashes the system. Nothing in initrd now:
- boot.initrd.kernelModules: empty (nothing touches RP1 early)
- boot.kernelModules: vc4, panel_cwu50, rp1_dsi (stage-2)

-# run-integration.sh — Staging VM Integration Test Suite
-#
-# Verifies Docker daemon, compose stack, and service endpoint health.
-# Designed to run inside the staging VM as part of CI/CD pipeline.
-#
-# Usage:
-#   ./tests/run-integration.sh                  # all defaults
-#   ./tests/run-integration.sh --verbose         # detailed output
-#   ./tests/run-integration.sh --list-services   # print detected services and exit
-#
-# Environment variables (all optional):
-#   COMPOSE_DIR       Path to compose service directories  (default: /opt/infra/compose)
-#   COMPOSE_PROJECT   Docker Compose project name          (default: staging)
-#   STAGING_DOMAIN    Base domain for health checks        (default: staging.lazyworkhorse.net)
-#   SERVICE_LIST      Space-separated service dirs to check (default: auto-detect)
-#   HEALTH_URLS       Space-separated URLs for health checks (default: auto-detect from SERVICE_LIST)
-#   HEALTH_TIMEOUT    Curl timeout per check (seconds)      (default: 5)
-#   HEALTH_RETRIES    Number of retries per endpoint         (default: 1)
-#   HEALTH_INTERVAL   Seconds between retries                (default: 2)
