Display the two new virus states for letters

Precompiled letters can now have two additional states:
* pending-virus-check
* virus-scan-failed

Both new states should show in the notifications dashboard, and
virus-scan-failed should appear as an error state, with a descriptive
message. You should not be able to preview a letter in one of the two
new states, so the preview link has been removed for precompiled letters
in these states.
