processing a published valued on a subscribed topic is currently running
in a task that is not the task executing the main loop(). that's because
the espMqttClient(Secure) was constructed without arguments, which
selects the constructor with two arguments priority and core, both of
which have default values. that constructor selects
espMqttClientTypes::UseInternalTask::YES, causing a task to be created
in which context the MQTT client loop is executed.
MQTT subscribers assume they are running in the same context as the main
loop(). most code assumes exactly that. as the scheduler is preemptive
and very little (none at all?) code is interlocked, we have to make sure
to meet the programmer's expectations.
this changeset calls the MQTT client loop in the context of the main
loop() and enforces the use of espMqttClientTypes::UseInternalTask::NO.
* MQTT verbose logging: fix typo
this typo caused that verbose logging was always disabled for MQTT and
could not be enabled.
* webapp status: show MQTT verbose logging setting
* PowerMeter: gracefully handle non-float MQTT values
* PowerMeter: update _lastPowerMeterUpdate conservatively
update the timestampt only if the topic actually matched any
subscription and if the value could be parsed as a float.
* PowerMeter: unsubscribe before subscribing
* PowerMeter: organize subscriptions in a map
this allows for a slightly more elegant code and reduced amount of code
overall.
* PowerMeter: clean up header
* move private methods to private section of class declaration.
* remove unused member variable.
Make the administrative accesspoint timeout configurable. The default
value is 3 minutes, values from 0-99999 are possible, where 0 means
infinite (no timeout).

* DPL: implement verbose logging switch
* MQTT: implement verbose logging switch
* power meter: implement verbose logging switch
* Hoymiles lib: implement verbose logging switch
* cpp linting: "final" makes "virtual" and "override" redundant
... however, using only "final" is not as verbose.
adjust window-title and header from OpenDTU to OpenDTU-onBattery
Additionally change orientation of battery symbol to vertically centered
(looks nicer)

if the new calculated power limit is below the minimum power limit
setting, the inverter is shut down. the shutdown() function is called
every time this condition is detected, which is also true if the
inverter is kept shut down for longer. that happens while the battery
is charging in particular (solar passthrough off). there are other
cases.
in such cases we still want to get into the DPL status "stable". to be
able to determine this stable state, we must know if the call to
shutdown did actually initiate a shutdown or if the inverter is already
shut down.
we then can forward this "changed" or "not changed" info up the call
chain, where the loop() will know that the system is actually stable.
* fix another fixable "passtrough" typo
the typo in the config's identifier is not changed to preserve
compatibility while not spending the effort to migrate the setting.
* webapp language: prefer SoC over SOC
* DPL: implement solar passthrough loss factor
in (full) solar passthrough mode, the inverter output power is coupled
to the charge controler output power. the inverter efficiency is already
accounted for. however, the battery might still be slowly discharged for
two reasons: (1) line losses are not accounted for and (2) the inverter
outputs a little bit more than permitted by the power limit.
this is undesirable since the battery is significantly drained if solar
passthrough is active for a longer period of time. also, when using full
solar passthrough and a battery communication interface, the SoC will
slowly degrade to a value below the threshold value for full solar
passthrough. this makes the system switch from charging the battery
(potentially rapidly) to discharging the battery slowly. this switch
might happen in rather fast succession. that's effectively
trickle-charging the battery.
instead, this new factor helps to account for line losses between the
solar charge controller and the inverter, such that the battery is
actually not involved in solar passthrough. the value can be increased
until it is observed that the battery is not discharging when solar
passthrough is active.
