feat(home): integrate PagerView for tab navigation and add verification redirect

Replace custom gesture handling with PagerView component for smoother tab
switching on home screen. Add verification required redirects in API and
WebSocket services that automatically navigate users to the verification
guide when receiving VERIFICATION_REQUIRED error codes.

BREAKING CHANGE: API and WS services now require router to be set via
setExpoRouter/setRouter for navigation to work properly
