Eagerly read file data into memory via arrayBuffer() before constructing
FormData for the upload fetch. Clipboard-paste File objects from the MDX
editor reference transient browser data that may be discarded after the
paste event handler returns; streaming that stale reference in the fetch
body causes net::ERR_ACCESS_DENIED. Reading into an ArrayBuffer first
makes the FormData self-contained.
Also suppress the Radix UI "Missing Description" console warning on the
NewIssueDialog by setting aria-describedby={undefined}.

wire image upload into InlineEditor multiline mode, NewIssueDialog,
NewProjectDialog, GoalDetail, IssueDetail, and ProjectDetail
