mrcharles f9954fd9b4 refactor(switches): standardize all switch names to <site>-<rack>-<function>-<NN>
Rename all 5 switches across all layers (DNS, DHCP, device hostname,
conman console, ser2net, udev symlinks, repo files) to follow the
<site>-<rack>-<function>-<count> convention:
  pfv-core-sw01    → pfv-r5-core-01     (rack 5 core)
  pfv-tor3-mgmt    → pfv-r3-tor-mgmt-01 (rack 3 mgmt TOR)
  pfv-tor3-stor    → pfv-r3-tor-stor-01 (rack 3 storage TOR)
  pfv-r2-tor-top   → pfv-r2-tor-01      (rack 2 TOR)
  subodev-torsw01  → pfv-r6-mgmt-01     (rack 6 mgmt)

Dead switch (pfv-r2-sw, port 2007) removed from mapping.txt.
pfv-rrinfra-rtr unchanged (router, not a switch).

Device hostnames changed via conman. Configs regenerated on pfv-tsys4.
All .cmds files, validate-conman.sh, and AGENTS.md updated. [#369]

mrcharles 396349640f feat(netinfra): migrate DHCP from pfv-netboot to netinfra-01/02 with failover
ISC DHCP server with failover-peer (primary/secondary) deployed on
pfv-netinfra-01 (192.168.3.252) and pfv-netinfra-02 (192.168.3.253). Both
servers in "normal" state, load-balancing 333 active leases.

Migration details:
- Copied all 37 host reservations + subnet/pool config from pfv-netboot
- DHCP lease database copied from netboot for zero-disruption cutover
- DNS servers changed from 192.168.3.250 (netboot) to 252/253 (netinfra pair)
- NTP servers (252/253) added to DHCP options (netboot didn't hand out NTP)
- Netmask on both nodes fixed /24 -> /22 to match the network
- Webmin + DHCP module installed on both nodes (port 10000, SSL)
- pfv-netboot DHCP stopped + disabled
- Tested via sectestbed-sandbox (DHCP lease obtained from 252, verified DNS/NTP/gateway)
- Snapshot "pre-dhcp-migration" on sandbox as rollback point

Configs: netinfra/dhcp/dhcpd-{primary,secondary}.conf
Plan + results: netinfra/dhcp-migration.md
