Address PR #1925 feedback

[rileyseaburg]

Summary

Addresses code review feedback from PR #1925:

Changes

1. Fix element_selector handling (template_renderer.rs)

   • Added null check for element_selector before calling getElementById
   • Prevents potential JavaScript errors with empty/null selectors

2. Remove unnecessary cargo clean (extconf.rb)

   • Removed cargo clean call before build
   • Clean CI environment doesn't need cargo clean, and removing cached artifacts significantly increases build time

3. Extract mock request setup to helper method (form.rb)

   • Created build_controller_with_mock_request private method
   • Reduces code duplication between touchpoints_js_string and render_widget_css
   • Improves maintainability

Not Addressed (Out of Scope)

• Sleep in specs - Would require broader refactoring of test patterns
• Production migrations - Intentional design decision (migrations run separately)
• Sidekiq deploy strategy - Would require broader deployment architecture changes
• Staging rake task syntax - Would need verification in staging environment
