Fix Safari NotAllowedError when generating a public sharing link

[Copilot]

Safari blocks navigator.clipboard.writeText() with NotAllowedError when it is called after an await in an event handler, because the user-gesture context is lost across the async boundary. In ShareRestrictionModal, the clipboard write happened after await createPermissions(...), so it always failed on the first click in Safari.

Changes (cozy-sharing — packages/cozy-sharing/src/components/ShareRestrictionModal/)

• ShareRestrictionModal.jsx — restructure handleClick to build a Promise<Blob> for the URL without awaiting it first, then pass that promise directly to copyToClipboard. The clipboard API call is now initiated synchronously within the click handler; only the content resolution is async.

• helpers.js — extend copyToClipboard to accept string | Promise<Blob>. When a Promise<Blob> is received and ClipboardItem is available, use navigator.clipboard.write([new ClipboardItem({...})]) instead of writeText. Safari supports this pattern: the permission check happens at call time (synchronous, within the gesture), the blob is consumed when the promise resolves.

// Before — clipboard write happens after an async gap; fails in Safari
const { data: perms } = await createPermissions(...)   // ← async gap
const url = generateWebLink(...)
await copyToClipboard(url, { t, showAlert })            // ← NotAllowedError

// After — clipboard write initiated synchronously; content resolved async
const urlBlobPromise = createPermissions(...).then(({ data: perms }) => {
  const url = generateWebLink(...)
  return new Blob([url], { type: 'text/plain' })
})
await copyToClipboard(urlBlobPromise, { t, showAlert }) // ← ClipboardItem + Promise

These changes belong in linagora/cozy-libs. The fix is fully specified here; a developer needs to apply it there and cut a new cozy-sharing release, after which twake-drive can bump its dependency.
