- `Setup a new Keycard with an existing account` flow improved
- code review comments applied
- Qml part updated due to the latest `StatusListItem` changes in `StatusQ`
Keycard implementation affected onboarding/login flows.
- new user - first run - new keys into keycard
- new user - first run - import seed phrase into keycard
- old user - first run - login importing from keycard
- login the app using keycard
Fixes: #5972
- 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
