Two issues occurred during upgrades:
1. Gancio config.json lost when Docker volume name prefix changes
(e.g., changemakerlite_ vs changemaker-lite_). Gancio finds existing
DB but no config and enters restart loop. Fix: verify_gancio_config()
checks the volume and regenerates config.json from .env if missing.
2. mkdocs-site-server (LSIO nginx) returns 403 after upgrade because
the anonymous /config volume shadows the ./mkdocs/site bind mount.
Fix: docker compose rm -sf the LSIO container before up -d so the
anonymous volume is recreated fresh.
Also adds Gancio and MkDocs site health checks to Phase 6 verification.
