Fix ScrollView content obstruction by tab bar on iOS

This commit fixes the issue where ScrollView content at the bottom of screens was being hidden behind the tab bar.

## Changes
- Added .safeAreaInset(edge: .bottom) to all main tab ScrollViews
- Increased bottom padding to AppSpacing.xxxl (64pt) for better spacing
- Removed .ignoresSafeArea(edges: .bottom) from AllTasksView which was causing issues

## Files Updated
- ResidencesListView.swift: Fixed residences list scrolling
- AllTasksView.swift: Fixed task columns horizontal scrolling
- ContractorsListView.swift: Fixed contractors list scrolling
- WarrantiesTabContent.swift: Fixed warranties list scrolling
- DocumentsTabContent.swift: Fixed documents list scrolling

## Technical Details
The .safeAreaInset modifier ensures ScrollViews properly account for the tab bar by:
- Automatically adjusting content insets for safe areas
- Allowing content to scroll fully above the tab bar
- Preventing content from being obscured

All tab views now provide smooth, unobstructed scrolling experience.
