fix: azulfiledownload: accept ref so it can be used as a tooltip child without a span wrapper (#944)

[frano-m]

Summary

• AzulFileDownload returned a <Fragment> and didn't accept a ref, so MUI Tooltip could not forward its anchor ref to a DOM node. Consumers worked around this by wrapping the component in a <span> at the call site.
• Wrap the component's contents in a single <span> and accept ref on the props interface (React 19 ref-as-prop — no forwardRef wrapper needed). Consumers can now use <AzulFileDownload ... /> directly as a Tooltip child.

Layout impact

None expected. The new <span> is inline by default and the IconButton inside is inline-flex, so the rendered DOM occupies the same flow position it did when the IconButton was a direct child of the table cell. The hidden anchor is still display: none. No findable-ui selectors target a direct-child IconButton in a way that would be affected by the new wrapper.

Test plan

• npm run check-format — clean
• npm run lint — clean
• npm run test-compile — clean
• npm test — all suites pass
• Smoke-test in data-biosphere — Files-column download tooltip renders correctly without a <span> wrapper at the call site, button still visually identical, download still triggers.

Related

• Surfaced by Fix ComponentCreator to Avoid Wrapping Children in Array for React.createElement #552 — the ComponentCreator children-array fix exposed the ref-forwarding gap.
• After this lands, data-biosphere's buildFileDownloadWithTooltip can drop its temporary <span> wrapper.

Closes #944

Pull request overview

Refactors AzulFileDownload so it can be used directly as an MUI Tooltip child. The previous Fragment root prevented Tooltip from forwarding its anchor ref to a DOM node, which had been masked by a bug in ComponentCreator that wrapped children in an array. This PR replaces the Fragment with a <span ref={ref}> and adds an optional ref prop using React 19's ref-as-prop pattern.

Changes:

• Replace top-level Fragment with a <span> wrapper that receives a forwarded ref.
• Add an optional ref?: Ref<HTMLSpanElement> to AzulFileDownloadProps and destructure it in the component.
