Changes

• Change DetailTableEdit.DetailDataPanel to wait for the button to go stale. The button is a more reliable check. A spinner may be slow to show up, and the tests never sees it. If a spinner does show up the button won't go away until the spinner does.
• Update ApiKeyDialog.getClipboardContent. This fails on WIndows with an 'unknown MIME type' error. This adds more logging and validates that as long as the clipboard isn't empty it will return a value. It returns an empty string if there is nothing in the clipboard.
• Remove getEditableRowIndices, getReadonlyRowIndices & getRowTypes from EditableGrid. These methods were initially added to accommodate the editable grid in the inventory module. In previous UI designs when adding or moving samples in storage the editable grid would be a mix of editable and non-editable rows (indicating positions already occupied). That is no longer the design, and these methods were adding no value.
• Updated EntityInsertPanel to accommodate the removed methods from the editable grid.
