Monitor: bump post-reEnable settle 1s->5s + retry idx=7 push

Field test: bay imaged end-to-end, Monitor saw Report IP log,
captured DeviceId (Phase 1 went COMPLETE on screen + QR rendered
from dsregcmd), but the idx=7 push to the PXE dashboard never
landed before the Intune-triggered LAPS-prompt reboot. Root cause:
Enable-NetAdapter + 1s sleep doesn't give Windows time to renew
DHCP + populate routes before Send-PxeStatus POSTs to PXE webapp.
Push silently caught (Send-PxeStatus has try/catch), next tick was
30s away, LAPS reboot fired in between.

Two changes:
1. Sleep bumped 1s -> 5s after Enable-NetAdapter so wired path is
   actually carrying traffic before we POST.
2. When the tick that did the re-enable is also the push tick,
   retry Send-PxeStatus up to 6 times with 2s spacing (~12s total)
   instead of one-shot-then-give-up. Surfaces the warning to the
   transcript if all attempts fail so we can diagnose next time.
