refactor(web): remove generated result React.FC

[lyzno1]

Summary

• Replace React.FC with an explicit Props annotation on the generated result component.
• Replace the React namespace import with the named memo import.
• Preserve the memoized export and every render path.

Dependency

This PR is stacked on #40279 only because all three PRs intentionally touch the same component in review order. It has no accessibility or icon behavior dependency.

Behavior contract

The component accepts the same props and remains memoized. There are no state, service, event-handler, or test changes.

Visual regression

No visual change is expected: JSX, DOM, classes, styles, layout, icons, ARIA attributes, and handlers are unchanged relative to #40279.

Reviewer focus: confirm the diff is limited to the React import, explicit props annotation, and memo export.

Validation

• Focused vp check: 0 warnings, 0 errors
• Focused accessibility lint: 0 diagnostics
• Focused Vitest: 3/3 tests passed
• Full pnpm check: 0 errors, 2058 existing warnings
• Diff relative to refactor(web): use css icon for generated result copy #40279: 1 production file, 4 insertions, 5 deletions

Closing during the accessibility stack audit. This layer only changes component typing or icon implementation, adds no user-visible accessibility contract, and carries independent visual/review risk. It can be reconsidered later as a separate cleanup, not as an a11y dependency.
