Refactor iOS and Android views into separate files

Organized view components by extracting composables and views into separate files following single responsibility principle.

iOS Changes:
- Split MainTabView → extracted ProfileTabView
- Split CompleteTaskView → extracted ImageThumbnailView, CameraPickerView
- Split ManageUsersView → extracted ShareCodeCard, UserListItem
- Consolidated task action buttons into single TaskActionButtons.swift file
- Split HomeScreenView → extracted OverviewCard, StatView, HomeNavigationCard
- Split AllTasksView → extracted DynamicTaskColumnView, DynamicTaskCard
- Split ContentView → extracted ComposeView, CustomView

Android Changes:
- Split ResetPasswordScreen → extracted RequirementItem component
- Split TasksScreen → extracted TaskPill component
- Created TaskDisplayUtils for shared helper functions (getIconFromName, hexToColor)

All extracted components properly organized in:
- iOS: Subviews/Common, Subviews/Task, Subviews/Residence, Profile
- Android: ui/components/auth, ui/components/task, ui/utils
