[EGD-6855] Add no modem notification on tethering

This commit provides the implementation of functionality that blocks
sms/calls notifications on home screen when tethering is active.
Previously, the notifications could be visible if the notifications
were visible prior to tethering activation.

By the design, the functionality should not clear the notifications,
just temporary hide them. That is achieved by implementation ot the
functionality in NotificationModel which is an UI presenter.

[EGD-6794] Fix display light settings

This commit provides the flowing fixes in display light functionality:
 - Settings-path bug causing lack of display light settings on "fresh"
 image. Solved with proper paths definition
 - Invalid settings after phone restart. Solved with proper handling
 of enums and booleans on the Event manager side.
 - No turning off light just after turning on light functionality with
 manual brightness setting in ApplicationSettings bug (required
 another key press to start timer that turns off the light after 5s).
 Solved by starting timer explicitly on Action::turnOn
 - No turning off light just after turning on the phone bug (required
 --as above --). Solved by starting timer explicitly on `Settings
 ValueChange` callback with Action::turnOn.
 - No autoMode until user entered `AppSettings::DisplayLight` Window.
 Bug caused by curve parameters being provided by the window rather
 than on the functionality back-end initialization.

 Commit also provides some code cleanup
