NFC tap to sign in

Create a custom embedded device that accepts NFC taps and can write info to NFC tokens via Zigbee

Set up shop home assistant service to broker zigbee data between the device and the sign-in display

Increase number of gunicorn workers to support long-running handlers

Add a persistent websocket handler that listens for NFC tap actions and triggers the sign-in flow

Modify the sign-in page to indicate when NFC tap is offline (MQTT disconnected, tap device healthcheck failing, too many workers occupied etc.)

Limit the maximum number of gunicorn workers running persistent handlers

Enforce cross-worker ratelimit on Neon web requests

Pair NFC tap device to phaven HA server

Create automation to receive NFC tap and forward to MQTT

Test with ?nfc=1 on browser page

Deploy channel groups to prevent duplicate MQTT message handling

Add timeout on NFC tag writing to prevent accidental overwrites

Update /welcome UX to do NFC token registration / publish MQTT event

HA automation to receive protohaven_api MQTT message

Switch to using Neon ID stored on the device (instead of email) for "more correct" sign in. May require changing account cache to allow lookup by ID.
