Fixes#6609
The menu was lost because it used to be set as part of the ScrollView background, but it got changed to a Flickable as part of the fix to the scrolls being not smooth.
Anyway, background doesn't exist on Flickables, so I removed it and moved the MouseArea to the CommunityColumnView instead.
- fix system appearance preview being cut off
- bring the panel close to UI design (I haven't changed the common
stuff like headline fonts, overall margins, etc)
Closes: #6623
Users model has to be sorted by online status first, otherwise
`UserListPanel` sections will be duplicated. That's because:
> Note: Adding sections to a ListView does not automatically re-order
the list items by the section criteria. If the model is not ordered by
section, then it is possible that the sections created will not be
unique; each boundary between differing sections will result in a
section header being created even if that section exists elsewhere.
fixes: #6563
Currently there is no need in the app for creating a pass via `CreatePasswordModal`
removed that support from the modal to avoid confusion about its usage.
- startup, login and onboarding modules merged into the single one
- `State` class introduced which is the base class for all states, every state
determines what is the next state in each of 3 possible actions, and what
is the previous state, if it has previous state
- `StateWrapper` class is introduced as a convenient way to expose
`State`'s props and deal with them on the qml side
- startup module maintains states as a linked list and there are few convenient
methods to move through the list `onBackActionClicked`, `onNextPrimaryActionClicked`
`onNextSecondaryActionClicked`, `onNextTertiaryActionClicked`
- redundant code removed
Fixes: #6473
- handle `SOURCES` recursively, rather than spelling all the paths out;
most of them were outdated and some still missing
- let the Python script skip existing translations (in case we need to
manually add plurals)
- updated qml_en.ts as a result of these changes
