Add SMAModbus.device_info() from the SMA profile type label - #175

Conversation
Reads Nameplate.Model/Vendor/SerNum/PkgRev from the SMA unit ID (default 3), so the serial identifies the same device as SMAWebConnect.device_info(). Move the packaged l10n loading into helpers so both transports translate the model and vendor tags the same way. Resync uv.lock to 1.1.8.

First step towards reading measurements over Modbus next to WebConnect: read the device info from SMA's own Modbus profile.
SMAModbus.device_info()reads the type label (Nameplate.Model, Vendor, SerNum and PkgRev at 30053–30059) fromsma_unit_id(default 3) and returns the sameDeviceInfoasSMAWebConnect.device_info(). The serial matches across both transports, so a client can check that a Modbus endpoint is the device it already knows. Modbus has no device name, soDeviceInfo's fallback name is used.0xFFFFFFFF, and tag values use the lower 24 bits with NaN0xFFFFFD. A unit that serves only NaN (unit 1 on an inverter) raisesSmaReadException.SmaReadException(exception response),SmaTimeoutExceptionandSmaConnectionException.SMAWebConnectintohelpers.load_l10n(), so both transports translate the model and vendor tags the same way. WebConnect behaviour is unchanged.uv.lockresynced to 1.1.8.Tested against a live STP5.0-3SE-40 (firmware 4.08.39.R):
DeviceInfo(type='SUNNY TRIPOWER 5.0 SE', manufacturer='SMA', sw_version='4.8.39.R'), the same values as WebConnect (with thesw_versionfix from the other PR).
