Make project token sorting and normalization a little less hacky

Summary:
Ref T8510. Use "\n" as a delimiter between name sections. Specifically, project "AAA" with tag "zzz" should be a better match for query "AAA" than project "AAA BBB" is.

Make use of this delimiter slighlty more obvious in the UI.

Test Plan:

• Created projects "Phacility" and "Phacility Core Access".
• Typed "Phacility".
• Before patch: first hit is "Phacility Core Access".
• After patch: first hit is "Phacility".
• Viewed debugging output table, saw visual explanation of behavior.
