flutter: const constructors cleanup (batch 1)

Scope

• Safe, no-behavior-change const optimizations where analyzer flagged prefer_const_constructors.
• Focused on widgets: invite_member_dialog.dart initial pass.

Changes

• invite_member_dialog.dart: make TextStyle const in _buildInfoRow where values are compile-time constants.

Why

• Reduces rebuild cost and analyzer noise without changing runtime behavior.

Validation

• Ran flutter analyze — no blocking errors.
• Ran flutter test — all tests passing (10/10).

Next

• Batch 2: broaden const constructors within widgets and ui/components where clearly safe.
• Separate PRs for deprecated API migrations (e.g., Share→SharePlus) and context-safety warnings.

Pull Request Overview

This pull request performs const constructor optimizations and API migration updates across Flutter and Rust codebases. The primary focus is reducing rebuild costs through const constructors while also migrating from deprecated Flutter APIs.

• Make compile-time constant constructors const to optimize widget rebuilds
• Replace deprecated withOpacity() calls with withValues(alpha:) API
• Update method signatures to include BuildContext parameters for proper context usage
• Add integration tests for auth registration routes with family/ledger creation validation

Remove the redundant const keyword. The parent const Center already makes the child widget const.

Suggested change

	child: const CircularProgressIndicator(),

The SizedBox should be const since all its properties (width, height, child) use compile-time constants. Change SizedBox( to const SizedBox(.

[Copilot]

The SizedBox should be const since its width is a compile-time constant and the Text widget uses string interpolation that could be evaluated at compile time for static labels. Consider making this const SizedBox( if the label parameter is always a compile-time constant.

[Copilot]

The SizedBox should be const since its height is a compile-time constant. Change SizedBox( to const SizedBox( to be consistent with the const optimization goals of this PR.
