Updated document creation modal styling to match issue creation modal polish. **Changes made** (server/templates/modals/document_form.html): - Changed modal title from 'New Document' to 'Create Document' - Updated close button: class 'close-btn' → 'modal-close', added type='button' - Changed all 'field-group' → 'form-group' - Added 'form-label' class to all labels - Added 'form-control' class to all inputs, selects, and textareas - Added 'form-help' elements for Entity ID and Tags fields - Added autofocus attribute to title input - Moved form wrapper inside modal structure (consistent with issue_form.html) **Verification**: - All tests passed (1165 passed, 39 skipped) - Deployed to trckr.roboalch.com - Visual verification via screenshots: Both modals now have consistent styling with proper form-group/form-control/form-label classes, same button styling, and consistent spacing Screenshots saved to /tmp for comparison: - /tmp/document_modal_after.png - /tmp/issue_modal_for_comparison.png
