Features:
- Add BLE disconnect simulation to test client reconnection behavior
- Support immediate disconnect, timed advertising pause, and full BLE teardown
- Add preset test buttons in admin UI (Quick Drop, 5s Pause, BLE Restart, 10s Restart)
- Add simulate_ble_disconnect MCP tool with duration_ms and teardown params
- Add POST /devices/{id}/disconnect API endpoint
Fixes:
- Fix treadmill distance not updating in admin UI (publish values periodically)
- Fix HR variation sending to non-heart_rate devices
- Fix BLE connection ID 0 being treated as "not connected"
- Clean up misleading startup log messages
Firmware: 1.1.0, API: 1.4.0, UI: 1.5.0

Firmware:
- Fixed WiFi reconnection bug after power cycle by adding WiFi.persistent(false)
and disabling auto-connect/auto-reconnect
- Fixed AP mode not broadcasting by properly handling WIFI_AP_STA mode transitions
- Refactored to service-oriented architecture:
- device_state: Central state management with event callbacks
- config_service: NVS persistence (renamed from config_manager)
- wifi_service: WiFi STA/AP management (extracted from main.cpp)
- mqtt_service: MQTT client and message routing (extracted from main.cpp)
- ble_service: BLE GATT services (renamed from ble_services)
- web_service: HTTP configuration portal (renamed from web_portal)
- main.cpp reduced from ~470 lines to ~60 lines (thin orchestrator)
- Each service is self-contained with setup()/loop() pattern
Backend:
- Added heart rate variation endpoint
- UI improvements
