docs(wiki): full IX server inventory from live SSH
Expand wiki/systems/ix-server.md with a 2026-06-05 live SSH inventory:
- Host: CloudLinux 9.7, cPanel/WHM 134, 64-core Xeon Gold 6130, 62 GiB,
4.4 T /home; Apache 2.4.67, MariaDB 10.11.16, ea-php 5.6-8.5,
Exim 4.99.4, Dovecot 2.4.2, BIND 9.16.
- 72 cPanel accounts / 185 domains / 101 WordPress; full account ->
primary-domain -> disk map (the "where does client X live" reference).
- ACG subdomain docroots (radio, community/Flarum, analytics/Matomo,
portal, support, etc.) under the azcomputerguru account.
- GuruRMM agent enrolled (gururmm-agent.service).
- Backups appear unconfigured (/backup ~178M vs 1.6T /home) - flagged.
- SSH key auth from GURU-5070 now works; updated reference_ix_server_access
memory (was stale: claimed key auth not set up) + index summary.
