Handle View Mode for Group and Repeatable Components

[andrewbrazzatti]

We currently don’t handle RepeatableComponent or GroupComponent in the visitor translation. This follow‑on issue should add support for these component types, with a preference for translating them at the top level (instead of recursively handling each subcomponent individually) if feasible.

Preferred translation behavior

• RepeatableComponent → render as HTML unordered list (<ul><li>…</li></ul>)
• GroupComponent → render as a group of key/value pairs in HTML
• RepeatableComponent containing a GroupComponent → render as an HTML table

Acceptance criteria

• Rendering exists for RepeatableComponent and GroupComponent in the visitor translation output
• Top‑level translation approach is used if it can cover the above behaviors cleanly
• Nested RepeatableComponent + GroupComponent case produces a table layout
• Output is predictable and consistent with existing visitor HTML conventions
