Query z s dispo lastUsed

Query z s dispo lastUsed is one of the queries in CFE used to maintain the s_dispo table. It has a companion Query z_s_dispo inactivatable.

This query will show when an entry in s_dispo table was last used for any of the 4 fields this table supplies. If it has not been used in a while it might be possible to inactivate it to clean up the dropdown. But it might also need to stay because the location simply isn't used very often.
