Bug/mobile 14

* When logging in with PIN, a broken layout appears for a sec or so. fixes #2048
* A short delay after input the last PIN number. fixes #2042
* Back link as a button. fixes #2029
* Fixes of some unlogged layout issues.
* Swipe action to change pages (using bottom bar menu as reference). 
* Swipe action to show/hide sidebars. fixes #2010
I would prefer that swipe only pull the sidebars, not to be used to change tabs on a given wallet.
