Revive project at new apartment — fixes, SSID update, gitignore

WiFi/firmware:
- SSID updated to botnet in both node and ble_node config.h
- Stale coordinator comment removed from node/config.h

Coordinator fixes:
- BLE-only nodes now visible in dashboard sidebar and node detail
  (build_nodes was querying beacon_events only; BLE nodes have no beacons)
- ble_events and heartbeat_events added to pruning cycle
- ble_events table added to ensure_schema() in dashboard
- confidence column dropped from beacon_events (always 'high', never queried)
- Ingestor commits batched per packet instead of per store call
- wal_autocheckpoint=500 added to ingestor DB connection (writer was missing it)
- python3 -u added to both service ExecStart lines (stdout was buffered,
  logs not appearing in journalctl)

Repo hygiene:
- .gitignore added (events.db, __pycache__, build artifacts)
- events.db removed from git tracking
- README updated: new apartment, node table, active investigations,
  BLE observations labelled as previous-location data, status checklist

+
+### BLE data summary (previous location)
+
+Data collected from BLE launch (2026-04-26) to project shutdown (2026-05-02) — 6 days, 2 nodes (A1D700C4, F68D6E30).
+
+| Metric | Value |
+|--------|-------|
+| Total BLE events | 1,086,897 |
+| Unique MACs observed | 89,818 |
+| Public (stable) MACs | 1,392 |
+| Random (rotating) MACs | 88,426 |
+| Named devices identified | 1,486 |
+| Peak day | 2026-04-29 — 209,589 events, 18,308 unique MACs |

+| Node F68D6E30 (room 1) | 411,086 events, 46,906 unique MACs |
+
+**Manufacturer breakdown (top by event count):**
+
+| Company ID | Vendor | Events | Unique MACs |
+|------------|--------|--------|-------------|
+| 0x004C | Apple | 686,109 | 67,987 |

+| 0x0006 | Microsoft | 53,794 | 2,336 |
+| 0x0057 | Harman/JBL | 27,930 | 47 |
+
+Apple accounts for ~63% of all BLE traffic. The high Apple unique MAC count is mostly FindMy/AirTag MAC rotation — individual physical devices inflate the count significantly.

 ### Heap baseline
 
 BLE nodes floor out at **109–127K free heap** vs 222K+ for WiFi nodes. The ~100K difference is the BLE stack overhead (BLEDevice + BLEScan + coexistence controller). This is expected and stable — no downward drift observed after 21 hours. The WiFi-only queue flush model keeps heap use predictable.

+### Samsung SmartTag cluster
+
+Three stable public Samsung MACs (`8c:79:f5:a6:dd:c3`, `68:72:c3:bd:ed:6f`, `7c:64:56:84:e0:b3`) generate 30K–36K events each across all 6 days of BLE data. All share the same mfr_data prefix (`42040180...`) — Samsung's Galaxy Find Network advertisement format (type byte `0x42`). These are Samsung SmartTag2 trackers belonging to one or more neighbours; stable public MACs make them directly trackable. RSSI −73 to −100 dBm suggests they are in a nearby unit or parking area below.
+
+### Apple type 0x06 — persistent unknown device
+
+MAC `c7:73:2d:eb:1a:b1` (random but stable) generates 30,765 events across all 6 days with consistent daily volume of 3K–5K events. Apple type byte `0x06` does not appear in Apple's published proximity pairing spec; this is an undocumented continuity or accessory advertisement type. The MAC has not rotated over 6 days, which is unusual for a random-type address. Likely a HomeKit accessory or Apple TV in a neighbouring unit that advertises continuously. Best RSSI −83 dBm.
