fix: Multi-Step form styles should be consistent when only one gateway is enabled

[henryholtgeerts]

Bug Report

User Story

As an admin, I want Multi-Step form template styles to remain the same, even when only one gateway is enabled so that I can create forms with only a single gateway, and still provide a polished, cohesive donation experience.

Current Behavior

Currently, when an admin enables only one gateway, certain styles break. The donate button becomes off center, and some prominent checkboxes are made to be too narrow.

Expected Behavior

With only a single gateway enabled, the form should be styled consistent with how it appears when multiple gateways are enabled. Similarly, spacing (padding/margins) around payment fields, and prominent checkboxes should be even, when only one gateway is enabled.

Bug Type

• This bug describes functionality that once worked as expected in version X.X.X.
• This bug describes functionality that never worked as expected.
• I am not sure whether this functionality ever worked as expected.

Steps to Reproduce

1. Create a form using the Multi-Step form template
2. Enable only one single gateway
3. Enable fee recovery, and a newsletter opt-in
4. On the front-end, note the off center "Donate Now" button, and poorly sized checkboxes

Visuals

Acceptance Criteria

• "Donate Now" button is centered
• Prominent checkboxes are a consistent width
• Styles appear consistent with multiple gateways, and with a single gateway enabled
• Spacing between form elements is consistent with multiple gateways and a single gateway enabled
