Use a function typeahead for "projects" in Maniphest
Summary: Ref T4100. Collapse the five inputs into one.
Test Plan:
- Searched for a bunch of stuff.
- Used "Group By: Project", which is a bit of a special case and possibly tricky.
- Created an old query with all the fields, then updated; verified it was preserved/transformed correctly.
