4ec7aa50e8 sunspec: reconcile storage states from the registers actions write
onStorageBlockUpdated() fed chargingRate from wChaGra() and dischargingRate
from wDisChaGra(). Those are the gradients, in percent of WChaMax per
second, and read only on several inverters. The matching actions write
InWRte and OutWRte, in percent of WChaMax. The user wrote one quantity and
read back another.

Feed the two rate states from inWRte() and outWRte(), and keep the
gradients under names that cannot be mistaken for setpoints:
chargeGradient and dischargeGradient, read only.

enableDischarging was never reconciled either, while enableCharging was.
It stayed frozen on the last written value and drifted silently as soon as
the inverter changed StorCtl_Mod on its own. Reconcile both flags.

The mapping moves into SunSpecStorageLogic so it can be exercised on a
register dump without a running nymea.

abae49e058 sunspec: widen storage charge and discharge rate range
chargingRate and dischargingRate map onto InWRte and OutWRte of model 124,
which are int16 setpoints ranging from -100.00 to +100.00 percent of
WChaMax. Declaring them as 0..100 makes a forced charge structurally
inexpressible: nymea rejects the negative action parameter before it ever
reaches the plugin.

Also fixes the default value, which was the boolean false on an int state.

d87a132f23 sunspec: add failing tests for every acceptance criterion
One test per AC of specs/fronius-sunspec.md, named test_AC_<n>_<what>.

Definition criteria (value ranges, thing classes, defaults) are checked by
re-reading integrationpluginsunspec.json. Behaviour criteria run either on
a model 124 register dump fed to the real libnymea-sunspec model, or on the
pure logic units the plugin is about to grow.

All red at this point: sunspecstoragelogic and froniusrules do not exist
yet, so the suite does not compile. That is the expected starting state.

bb842eea55 sunspec: vendor plugin sources from nymea-plugins-modbus 1.15.2
Vendor the sunspec plugin into this repo so the Fronius work and the
upstream storage fixes can live here. Sources only: build artefacts and
generated plugininfo headers are excluded.

libnymea-sunspec is deliberately NOT vendored - the plugin must stay
rebasable on upstream nymea, so it links against libnymea-sunspec-dev.
sunspec.pri resolves it via pkg-config, with a NYMEA_SUNSPEC_PATH
override for a local sysroot, mirroring modbus.pri.

See sunspec/VENDORED.md.
