Viktor Barzin 0752bd49c8 kms: document native DNS auto-discovery (no client config needed) 
LAN clients with DNS suffix viktorbarzin.lan now activate with zero
configuration — Windows queries _vlmcs._tcp.viktorbarzin.lan SRV by
default and the chain resolves through vlmcs.viktorbarzin.lan to the
new 10.0.20.202 KMS IP.

DNS state (Technitium primary, replicated to secondary+tertiary by the
existing technitium-zone-sync CronJob every 30 min):
- _vlmcs._tcp.viktorbarzin.lan SRV 0 0 1688 vlmcs.viktorbarzin.lan
  (was: target=kms.viktorbarzin.lan)
- vlmcs.viktorbarzin.lan A 10.0.20.202   (added)
- kms.viktorbarzin.lan A 10.0.20.200      (unchanged — still the
  Traefik LB for the user-facing website at kms.viktorbarzin.lan/)

vlmcs.viktorbarzin.lan was added as a dedicated KMS-server hostname
rather than retargeting kms.viktorbarzin.lan so the LAN-direct website
keeps working without depending on hairpin NAT through pfSense.

Verified end-to-end on WIN10Pro-DS32 (192.168.1.230):
slmgr /ckms → slmgr /ato → "Product activated successfully" with
"KMS machine name from DNS: vlmcs.viktorbarzin.lan:1688" and
"KMS machine IP address: 10.0.20.202". Real client IP 192.168.1.230
appears in vlmcsd log and in the slack-notifier sent line; second
activation within the dedup window correctly increments
kms_activations_dedup_skipped_total.
