Document undocumented services on london-a (#29)
Audit of london-a rc.conf found several services running but not
captured in host_vars or docs: cloudflared, InfluxDB, Redis,
PostgreSQL, and libvirtd.

- InfluxDB: only _internal db, completely unused
- Redis: empty keyspace, unused
- PostgreSQL: has pez_vps db from a dead project, needs data review
- libvirtd: zero VMs, related to same dead project
- cloudflared: running tunnel 168eccae, config now captured

Also documented the weekly ZFS scrub cron (Sundays at noon) which
is in root's crontab but not ansible-managed.
