* fix: DPL: start discharging at night logic error
the switch "always start discharging battery at night" would cause to
stop discharging the battery when there was solar power and the battery
was discharged below the start threshold.
this change introduces a nighttime discharging boolean variable, which
is enabled the instant we decide to start a battery discharge cycle due
to nighttime havin arrived. we reset this variable as soon as it is
daytime (solar power available). in that case, we allow discharging the
battery if the start threshold was reached. this can actually be the
case if the battery is charged with cheap electricity during the night.
removed comments as they merely spell out what the if statement already
expresses quite nicely.
* use SunPosition.isDayPeriod() to check for daytime

this changeset adds support for parsing the MQTT battery provider's SoC
and voltage topics' payloads as JSON to extract a numeric value at a
configurable path.
* show battery voltage, current, and power in live view header (the "totals")
* show battery current and power in extra card
* use soc and current precision in live view
* BatteryStats: do not knowingly publish invalid data: not all battery
providers know all values the base class manages. make sure to
prevent publishing invalid values.

This breaks existing HASS automation, as entity names and MQTT topics change!
* include dtu-unique-id in DPL MQTT HASS topics to allow multiple DTUs to be controlled
* fix filename "src/MqttHandlVedirectHass.cpp"
* refactor: use values from 'MqttHandleHass', add 'via_device' to all HASS devices
* set step size for power limiter voltage values
Hoymiles inverters allow setting relative limits with a precision of 0.1 %.
this changeset allows to utilize this precision.
* preserve accuracy when decoding power limit
* Web API: process floating point limits
* MQTT: process floating point limits
* use appropriate accuracy for limits in web UI
* HASS: step for relative inverter limit is 0.1 %
we previously used the mutex to protect writing the target variable.
however, we would only do that for the old usecase, where a plain float
value in Watts was expected as the topic's payload.
make the MQTT power meter pre-selected when editing power meter settings
for the first time. the MQTT power meter is the most efficient and hence
preferred power meter implementation.
enabling the HTTP+JSON power meter without enabling at least one value
makes no sense, so value 1 has always been treated as "always enabled".
while doing the power meter refactoring, however, a regression was
introduced that would hide the settings for value 1 in the web UI until
the power meter settings would be saved, which they cannot be due to
missing settings for value 1.
