fix(forms): reset group fieldset padding

[mattrothenberg]

Summary

• reset native fieldset padding in Radio.Group and Checkbox.Group so host styles cannot add unwanted group spacing
• add focused regression coverage for both group components

Validation

• pnpm --filter @cloudflare/kumo lint

• pnpm --filter @cloudflare/kumo exec vp fmt --check src/components/radio/radio.tsx src/components/radio/radio.test.tsx src/components/checkbox/checkbox.tsx src/components/checkbox/checkbox.test.tsx

Review notes

• Confirming PR #801 and inspecting its diff, existing reviews, and the Kumo package review conventions.
• PR metadata confirms #801; the checked-out repository lacks origin/main, so I will compare the authoritative trigger commit directly through GitHub and run the targeted component tests locally if dependencies permit. The current PR has no submitted reviews.
• The authoritative commit a2b0daf changes only the two group fieldsets, adds a patch changeset, and adds/updates their tests; there are no existing inline review comments to avoid duplicating.
• The targeted test command could not run because pnpm is not installed in this runner. I am checking class-merging and stylesheet generation paths to verify the important padding reset reaches the rendered fieldsets.
• Diff validation for a2b0daf passes with no whitespace errors. The !p-0 utilities are present on both rendered Fieldset.Root elements and are included in the standalone Tailwind stylesheet input; no behavior, accessibility, or API regression was identified.
• GitHub reports no required checks for the branch. The PR’s only post-trigger commit is a merge from main; the reviewed change remains the authoritative a2b0daf patch.
