fix: add profile flags to all docker compose commands and complete env vars

All services in docker-compose.yml are behind profiles (dev/ops), but the
maintenance scripts called docker compose without --profile, so no services
were detected or built. Added --profile dev --profile ops to BuildAll.sh,
StatusCheck.sh, and all relevant maintenance.sh commands.

Also:
- Added missing env vars for 8 newer servers to .env.example (beszel, gitea,
  grafana, ha, limesurvey, linkwarden, superset)
- Fixed maintenance.sh validate to use validate-all.sh instead of nonexistent
  validate-mcp.sh

.env.example
