Bug 30333: Move view actions on acquisitions receipt summary page into menu

This patch moves the "views" group of links (MARC, Card, and Order) into
a menu button. The patch also makes some corrections to the modal markup
and handling to fix a display error.

To test you must have a basket or baskets with multiple titles on order,
both received and pending.

- Apply the patch and go to Acquisitions -> Vendor -> Receive shipment
  -> Receive a new shipment (or open an existing invoice).
- In the list of pending orders:
  - Test the 'View' menu for multiple titles. The 'Order,' 'MARC,' and
    'Card' menu items should work correctly.
