Android: split large UI files into per-component files

[dkhalife]

Summary

Break down large Android UI files so each component lives in its own file.

New files - ui/components/

• GroupHeader.kt - Collapsible group header row in task list
• TaskItem.kt - Task card with complete/skip/delete actions
• TaskChips.kt - DueDateChip, RecurrenceChip, NotificationChip, LabelChip
• DateTimePickerRow.kt - Two-step date + time picker dialogs
• RecurrenceSection.kt - Full recurrence selector (frequency type + sub-modes)
• SchedulingSection.kt - Rolling vs from-due-date radio buttons + end date toggle
• NotificationsSection.kt - Notifications enable toggle + per-trigger checkboxes
• LabelItem.kt - Label list row with edit/delete buttons
• LabelDialog.kt - Create/edit label dialog with name field and color swatches

New files - ui/utils/

• TaskFormatters.kt - parseDueDate, formatDueDate, formatDistance, recurrence text helpers, rememberTickingNow
• DateTimeUtils.kt - parseIsoDateTime, toIsoString, toDisplayString

New files - ui/navigation/

• Routes.kt - Screen sealed class + Routes object (extracted from AppNavigation.kt)

Reduced files

File	Before	After
TaskListScreen.kt	445 lines	99 lines
TaskFormScreen.kt	666 lines	318 lines
LabelsScreen.kt	223 lines	107 lines
AppNavigation.kt	200 lines	191 lines

No functional changes - purely structural.

Pull request overview

Refactors the Android UI layer by extracting previously inlined Compose UI blocks and formatting/date helpers into dedicated component and utility files, reducing screen file sizes while keeping behavior the same.

Changes:

• Extracts task list UI pieces (group header, task item, chips) into ui/components/.
• Extracts task form sections (date/time picker, recurrence, scheduling, notifications) into ui/components/ and date/time helpers into ui/utils/.
• Extracts navigation route definitions into ui/navigation/Routes.kt and updates AppNavigation imports accordingly.
