ca8dd6a525 Add TP-Link SG2428LP switch hardening as repeatable IaC + static IP/DNS
Secure and configure the SG2428LP managed switch (10.0.0.10) as repeatable
Ansible, driven from the control node over SSH by an expect engine.

- tplink_switch_harden role (verified JetStream CLI syntax): HTTP off/
  HTTPS-only, Telnet off, SSH v2, SNMP off, RSTP + loopback-detection,
  then copy running-config startup-config (persist).
- playbooks/harden_switch.yml + [switches] inventory group; dry by default,
  -e switch_apply=true to apply, -e switch_apply_network=true for addressing.
- Static mgmt IP 10.0.0.10/24 (off DHCP, below the .20-.199 pool), gw 10.0.0.1,
  hostname sg2428lp.
- op -> ansible-vault bridge (etc/set-switch-1password.sh); admin password in
  group_vars/switches/vault.yml.
- DNS: A/PTR sg2428lp.prole.org -> 10.0.0.10 (records added to dns.yml/ptr_records).
- Fix: tag the samba_reverse_dns zone-list set_fact so tag-limited runs define
  samba_reverse_zones.

Engine notes (hard-won): forces password-only SSH auth (the switch drops
publickey-first logins); always saves config (unsaved changes revert on reboot).
