Starred view: colour-only priority, dependency ordering

[sohamM97]

Summary

• Remove bold from high-priority children in starred views — accent colour tint alone provides enough visual distinction
• Reorder children by dependency chains so blocked tasks appear after their blocker, matching All Tasks view
• Applied in both tree preview cards and expanded dialog
• 12 new reorder tests, 6 updated childTextStyle tests

Test plan

• 1257 automated tests pass (12 new reorder + 6 updated style)
• Manual test: high-priority children show colour only, no bold
• Manual test: blocked tasks appear after blocker in tree preview
• Manual test: blocked tasks appear after blocker in expanded dialog
• Manual test: ordering matches All Tasks view

Issue found in docs/UI_VIEWS.md: incorrect function name

The Expanded dialog description references _reorderByDependencyChains() (with a leading underscore), but the actual function introduced by this PR is the public reorderByDependencyChains() (no underscore). In Dart, a leading underscore denotes a private symbol — _reorderByDependencyChains does not exist in starred_screen.dart; the only function with that private name is an unrelated method in task_provider.dart.

Per CLAUDE.md: "Verify before documenting. Before writing any factual claim in a doc (docs/, CHANGELOG, comments), verify it exists in the codebase first."

The actual function is defined here:

task-roulette/lib/screens/starred_screen.dart

Lines 66 to 69 in 5084857

	final treeEntries = await Future.wait(starred.map((task) async {
	final children = await provider.getChildren(task.id!);
	var allActive = children
	.where((c) => c.completedAt == null && c.skippedAt == null)

Fix: Change _reorderByDependencyChains() to reorderByDependencyChains() on this line of docs/UI_VIEWS.md.
