Add support for missing form-control input types

[FlorianRappl]

Description
Several form-control types are missing or incomplete in rendering/behavior.

Scope

• Identify unsupported <input> / related control types currently falling back incorrectly.
• Implement rendering/layout/interaction behavior for those types within renderer scope.
• Document intentionally unsupported types or partial behavior.

Acceptance criteria

• Previously missing control types render with distinct, type-appropriate behavior.
• Unsupported remnants are explicitly tracked with follow-up items.
• Regression tests added for each newly supported type.
