Book deliveries and pair BLE devices

**Deliveries** (Deliveries tab) are scheduled handoffs. Examples: a hotel forwards a guest's bag to a different property; an airline runs delayed-bag delivery to the passenger's home.

To book:
1. Deliveries tab → "+ Book delivery"
2. Select the bag(s) — multi-select fine
3. Recipient + address + window (specific time or a range)
4. Carrier (your own staff, or a marketplace partner if enabled)
5. Save → delivery is scheduled; the assigned operator gets it in their queue.

Wally tool `luggage_bookDelivery` does the same from chat.

**BLE devices** (Devices tab) are optional. Pair a Bluetooth/UWB beacon to a bag to enable proximity tracking — useful for finding a bag fast in a large room (luggage hall, hotel back-of-house).

To pair:
1. Devices tab → "+ Add device" — device id, type (BLE / UWB), battery level
2. Open the bag → "Pair device" → pick the device id
3. Onboard scanners or operator phones running the Turtini app pick up the beacon and write proximity events (within ~10m). The Dashboard surfaces "bag last seen 2 min ago, Bay 3, signal strong."

Wally tool `luggage_lookupByQr` lets a staff member resolve a bag from chat ("Wally, where is bag LX-4429?") — returns the latest event + nearest device proximity.
