App: - New DeviceRole.solar with its own BLE session/protocol/state (SolarSession, VanAlignSolarProtocol, SolarState), mirroring the leveling sensor but deliberately not wired into the Live Activity. - BluetoothManager now keeps an in-memory history per metric (voltage, current, power) instead of a single primary-metric series; cleared on app restart by design, not persisted to disk. - DeviceDetailView shows a channel picker above the history chart when a device has more than one chartable metric. - AddDeviceView recognizes the solar service UUID during setup. - DemoData gets a simulated solar device so the integration can be checked in the simulator without hardware. Firmware: - Add esp32_ble_solar.yaml (Votronic solar charge controller over BLE) and simulated variants (esp32_ble_sim.yaml, esp32_ble_solar_sim.yaml) for testing without a vehicle. - esp32_ble.yaml: set flash_size/psram for the ESP32-S3 N16R8 module.
