fix(drill-detail): decouple copy button from download permission

Copy was gated on canDownload, which hid the button for users who
lacked export permission but could still legitimately use the clipboard.
Gate Copy on canCopyClipboard (via usePermissions) and show the same
permission-denied tooltip pattern used by the sibling Explore pane
DataTableControls.
