People app and navigation + fixes

Index.js
- Fixed issue where incorrect pathname was set while not part of an organization.
- onNavigate(), fetchAppData(), getDefaultNetworkName(), and getDefaultAppName() all modified to account for user not being part of an organization (default path set to /my/dashboard)
- onNavigate() modified to properly set defaults for currentNetwork and currentApp, and modified to fix issue where app would crash when attempting to access nonexistent 'this.currentNetwork.data'
- onNavigate() now correctly switches currentApp

Home.js
- Changed ZStack to a VStack
- Replaced Jobs switch case with People
- Adjusted styling for AppMenu() and VStack height values
- Changed .onNavigate() from function() to () => {} for correct this binding
- !!!(TEMP FIX)!!!: Added extra rerender() call in an .onClick() after .onNavigate()

- Changed Forum's app icon to redirect from "/" to "/dashboard"
- Removed fixed styling to account for Home's new responsive VStack layout
