fix(frontend): give the share-mode radio buttons an enclosing radiogroup

[ManasBagul23]

Problem

In ShareAlbumDialog.tsx, the "This network" / "Internet" share-mode
toggle buttons declare role="radio" and aria-checked, but the wrapping
container is a plain div with no role="radiogroup" or accessible name.
WAI-ARIA 1.2 requires role="radio" elements to sit inside a
role="radiogroup" container — without it, screen readers announce each
button as an isolated control instead of a group of mutually exclusive
options with position context ("1 of 2").

Fixes #1529

Fix

Add role="radiogroup" and aria-label="Share mode" to the container div.

Verified

Added a regression test in ShareAlbumDialog.test.tsx asserting both mode
buttons are reachable via getByRole('radiogroup', { name: /share mode/i }).
Confirmed it fails against the pre-fix component (getByRole('radiogroup', ...)
finds nothing) and passes with the fix. Ran the full existing
ShareAlbumDialog.test.tsx suite (22 tests) — no regressions.

Summary by CodeRabbit

• Accessibility
  • Share-mode options are now presented as an accessible radio group named “Share mode,” making the group’s purpose clear to assistive technologies. The selected option remains available to change using the existing share-mode choices.

Walkthrough

The share mode selector now uses a controlled Radix radio group. Changes to the selected mode go through handleModeChange. A test verifies the “Share mode” group name and its Internet and This network radio buttons.

Addressed CodeRabbit's suggestion: swapped the manual role="radio"/aria-checked wiring for RadioGroupPrimitive.Root/Item (the same Radix primitive the dialog's own "Keep sharing" expiry selector already uses), rendering the existing pill button as the Item's child via asChild so arrow-key navigation now works and the visuals are unchanged. Full test suite (22 tests) still passes.
