frontend: find bar project filter is an All projects / All units select pair (#40)

The find bar reused the New Packet two-step picker, which put a project
search and a list of project cards inside the bar. It now has two selects
like the old build: All projects or one active project, then All units or
one of its units. A saved pick no longer in the active list still shows.

Closes #40
