Clean up widget code and update a dependency:
- Remove redundant const qualifiers and tidy widget children in several skeleton/header widgets for consistent style.
- Add super.key to TaxFormsProgressOverview, TaxFormStatusBadge, and AccountCard constructors.
- Simplify AccountCard by consolidating its constructor into a single const declaration.
- Minor fixes: adjust Image.onError parameter, reformat CircleAvatar/Icon construction in edit_profile_page.
- Add bloc ^8.1.4 to staff/authentication pubspec.
These changes are stylistic and aim to improve consistency and constructor patterns across the codebase.
