[Redesign] Put all ApplicationSearch results in an ObjectBox

Summary:
Ref T8099. In most cases we return either an ObjectList or AphrontTable, and can pretty up the UI in ApplicationSearch. There are a few edge cases, like PeopleUserLog, that can be cleanup up individually in the future, but look fine for now.
Also added 'setNotice' for AphrontTable for a few cases where we want to convey addtional information.

TODO: Seems we always pass a Pager Object, which tries to get displayed, I'll redesign that interaction in the future, probably by passing the Pager to the ObjectBox

Test Plan: Went throught most/all ApplicationSearch panels I could find, even edge cases look better.
