[Cleanup] Remove old sass

[phenchaw]

Removed sass dependency, tilt should use dartsass

Greptile Summary

This PR removes the sass gem dependency from aub-payroll.gemspec without adding a replacement SCSS engine. However, the project still contains an active style.scss template (lib/aub/payroll/summary_file/templates/style.scss) that is rendered at runtime via Tilt in html_generator.rb. Without a registered SCSS handler (provided by gems like dartsass-ruby or sassc), this will cause a runtime RuntimeError whenever a summary PDF is generated, breaking a core feature of the gem.

Critical issue: No replacement SCSS-processing dependency was added before removing sass.

Confidence Score: 1/5

• Not safe to merge — removing sass without adding a replacement SCSS engine will cause runtime failures when generating PDFs.
• The PR removes the only SCSS-processing gem (sass) while leaving active SCSS template rendering code in place. This will cause RuntimeError whenever html_generator.rb attempts to render style.scss via Tilt, breaking PDF generation — a core feature of this gem. No replacement dependency (e.g., dartsass-ruby, sassc) is provided.
• aub-payroll.gemspec — must add an SCSS engine gem before the sass removal is safe.

Missing SCSS engine dependency after removing sass gem

The sass gem is removed here, but no Dart Sass gem is added as a replacement. The project still has a style.scss template (lib/aub/payroll/summary_file/templates/style.scss) that is rendered at runtime via Tilt in html_generator.rb:

render 'style.scss', 'style.css'

This calls Tilt.new(template_path).render(self) at line 41, which requires a registered template handler for SCSS. Without a gem that provides an SCSS engine (such as dartsass-ruby), Tilt will raise a RuntimeError: Could not find Tilt template handler for 'scss' when this code executes, breaking PDF generation.

The fix should add a Dart Sass gem dependency:

Suggested change

	spec.add_dependency 'configurations', '~> 2.2.0'
	spec.add_dependency 'dartsass-ruby'
	spec.add_dependency 'configurations', '~> 2.2.0'
	end

Alternatively, sassc (LibSass) is also a valid SCSS processor.

Comment:
Missing SCSS engine dependency after removing `sass` gem

The `sass` gem is removed here, but no Dart Sass gem is added as a replacement. The project still has a `style.scss` template (`lib/aub/payroll/summary_file/templates/style.scss`) that is rendered at runtime via Tilt in `html_generator.rb`:

```ruby
render 'style.scss', 'style.css'
```

This calls `Tilt.new(template_path).render(self)` at line 41, which requires a registered template handler for SCSS. Without a gem that provides an SCSS engine (such as `dartsass-ruby`), Tilt will raise a `RuntimeError: Could not find Tilt template handler for 'scss'` when this code executes, breaking PDF generation.

The fix should add a Dart Sass gem dependency:

```suggestion
  spec.add_dependency 'dartsass-ruby'
  spec.add_dependency 'configurations', '~> 2.2.0'
end
```

Alternatively, `sassc` (LibSass) is also a valid SCSS processor.
