[App navigation] Implement primary bottom navigation

[mirunaioana-msc]

How it works now

Currently in the app the bottom navigation is not on the whole app and it is only displayed after an user clicks on a module from the homescreen.

How it should work

We should have primary bottom navigation for the entire app according to the Figma guidelines found here

"Home" should take you to the homescreen (Figma here)
"Manage" should take you to the Manage symptoms module (Figma here)
"Track" should take you to Track progress module (Figma here)
"Learn" should take you to Learn module (Figma here)
"Support" should take you to Support module (Figma here)
