[Dev] Executive Summary with no activities for MMIS APDs

[mirano-darren]

Describe the task here and link or add dependencies to any applicable issues...

MMIS APDs do not require activity 1 to be Program Administration and will no longer be automatically generated. Since a 0 activity MMIS APD is possible, we have to adapt the Executive Summary for that edge case.
