Closes the sell-to-friend gap where a buyer's freshly-reset device
would briefly display the seller's photos before the buyer reached
/setup/{mac} to claim. The firmware had no way to tell the server
"I just got reset" — now it does.
Flow:
- WiFi-setup completion (handle_connect in main.cpp) writes
NVS_KEY_JUST_PROVISIONED=1 alongside the SSID/PASS save.
- Every poll while the flag is set sends X-Just-Provisioned: 1.
- Server (DeviceImageController, paired commit on the webApp side)
responds with 204 + X-Interval-Ms when the binding is stale,
forcing the device to its setup-QR fallback. Once the user
re-claims via /setup/{mac}, the binding is fresh, and the server
answers with X-Claimed: 1 alongside whatever response code applies.
- Firmware clears the NVS flag on seeing X-Claimed: 1 — once
cleared, the device is back to normal long-stable polling.
Tests:
- PROV-A: flag set in NVS → header on the request
- PROV-B: no flag → no header (steady state)
- PROV-C: response with X-Claimed: 1 → flag cleared
- PROV-D: response without X-Claimed → flag stays (so the next
poll keeps signaling "not yet acknowledged")
