Move people list rendering into SearchEngine
Summary:
Ref T4986. One note:
- We have a separate "browse directory" capability, to provide some soft privacy for users of public installs. Respect that policy within the SearchEngine.
- Also restore some other icons I missed earlier.
Test Plan:
- Viewed people list.
- Build people panel.
- Verified people panel was just me without browse capability.
