Removal of Viewports on HAM2

Jordan, Jake Z, Owen H

Per FRS Ticket 38164, two viewports were removed off of HAM2 and replaced with Class A 10" CF blanks.

On the East Door, port A2F2 was an uncoated ZV-800 (SN 66), and on the West door A1F1 was a ZV-800 Coated SN (R009). These two viewports will be inspected on the bench and put into spares inventory if all looks okay and passes inspection criteria.

These two blank flanges will be added to the list for leak checking during pumpdown.
