[IP-694]: Fix recent dashboard widget ordering

[PuvaanRaaj]

Summary

• order Recent Expenses, Payments, Projects, and Tasks by descending primary key
• avoid Laravel’s default created_at ordering on models that disable timestamps
• add ordered-record regression coverage for each widget

Developer checklist

• References CHECKLIST.md rows: expenses, payments, projects, and projects/tasks
• Includes appropriate test coverage
• Follows service/DTO/transformer structure (no new inline logic)
• UI follows Filament & Livewire best practices
• Translations not needed
• Full php artisan test suite not run
• Ran vendor/bin/pint for changed files

Validation

• php artisan test Modules/Expenses/Tests/Feature/RecentExpensesWidgetTest.php Modules/Payments/Tests/Feature/RecentPaymentsWidgetTest.php Modules/Projects/Tests/Feature/RecentProjectsWidgetTest.php Modules/Projects/Tests/Feature/RecentTasksWidgetTest.php (8 tests, 16 assertions; existing PHP 8.5 deprecations only)
• vendor/bin/pint --test on the eight changed files

Closes #694

Summary by CodeRabbit

• Bug Fixes

  • Recent expenses, payments, projects, and tasks now consistently appear newest first.
  • Widgets display the latest records in the expected order.

• Tests
