[MOS-300] Remove unused variables

Remove unused variables from PVS Studio analysis

[MOS-269] Fix lock audio subsystem during voice call

Audio service is deadlocked on sentinel because IsBussy() method returns
that it's all the time bussy. Even though there is no ongoing audio
requested from either GSM or apps.

[MOS-296] Merge new master commits into merge-stable-wip

Merge new master commits

[MOS-296] Merge remote-tracking branch 'origin/stable'

Merge stable Harmony branch into merge wip branch

[MOS-256] Turn off torch driver when not in use

We save on power consumption ~0.7 mA.

[MOS-226] Moved algorithms and their data to separate classes

This way we have controll over what does what, and can test
them separatelly
Logging statistics update more and better data presented

[MOS-123] Added bluetooth authentication popups

Added bluetooth authentication popups with different
pair methods and process info display.

[MOS-221] DND - missing notifications

Add notifications for missing calls in DnD mode

[MOS-245] Fix errant spaces

It appears in the past a major edit was made but had used a regex to
change some text which resulted in an errant space between the
enumuneration/struct/class name and the scope resolution operator.
These errant spaces have been removed.

[EGD-8208] Post rebase and review cleanup

Style fixed, moved files to catalog, renames

[EGD-8208] Added stop audio route on async response

We get Token on play, and require it in stop. While we cant
stop sound by title & data set to play. And adding standard
handling causes either totally synchronous calls or requires
multiple additional guards it seemed like best use.
Fixed expectation for the same named Response, but meant for bell
Needed so that
- we ring only when needed
- we handle CLIP and RING properly
Applied style
Missed file added
Moved SML logger as it's usefull to some more common parts of code

[EGD-8208] Audio try to handle actual stop

Stopping all audio seems excessive

[EGD-8208] Fixed race condition on ring within call management

Now we get request for call and to end call in proper order

[MOS-234] Add Abc input mode to contact search

Abc mode was not selected as a default,
because it was not added in this input field.

[MOS-111] Added missing refresh conditions

Added missing refresh conditions.

[CP-1021] Add token field to Device Info API

Generating a device unique id
Returning device token generated from device unique id in DeviceInfo
Added test for device token in test_devic_info.py

[CP-1033] Add Outbox endpoint to service-desktop

Outbox endpoint will be used to provide notifications
about changes in messages/threads/calls during connection
with Mudita Center. This mechanism will ensure an efficient
data synchronization between Mudita Pure and Mudita Center.

[MOS-227] Fix DnD first call crash

fixed call when making first call from unknown number
when Pure is in DnD mode

[MOS-146] Baudrate change for cellular transmission

UART baudrate changed from 460800 to 115200
* lower power consumption by modem
* URC support on 24 MHz CPU instead of 132

[MOS-144] Fix Increased CPU usage

On the locked screen, while refreshing the screen,
the CPU woke up to the maximum frequency,
which resulted in an increased power consumption.
