Refactor duplicated dialog action logic

Centralize repeated dialog creation/action handlers into a helper to ensure consistent UX and error handling.

Why this matters

Prevents drift in copy, button order, and analytics hooks.

Bad vs. good

Side-by-side examples engineers can pattern-match during review.

Avoid

showDialog(context: ctx, builder: (_) => AlertDialog(actions: [TextButton(onPressed: onOk, child: Text('OK'))])); // repeated many times

Prefer

Future<void> showOkDialog(BuildContext c, String msg, VoidCallback onOk) {
  return showDialog(
    context: c,
    builder: (_) => AlertDialog(content: Text(msg), actions: [TextButton(onPressed: onOk, child: const Text('OK'))]),
  );
}

More snippets

Bad

AlertDialog(...) duplicated

Good

showOkDialog(context, 'msg', onOk)

Critical
Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Critical
Avoid Redundant `None` Comparisons
Identify cases where `x is None` or `x is not None` is used redundantly when `x` is always or never `None`. This may indicate a deeper logic issue.

High
Avoid Functions That Always Return the Same Value
Identify functions that return the same value regardless of input. This may indicate poor design or a logic error.
