refactor: one front door

Start Investigation is gone. The daily review is the only way a case is
born — "she isn't asked" should not ship with a button for asking her. A
person still steers Ava, but only about something she already found:
Send Back to Ava carries the note.

Removed the ask-a-question screen, route and ghost button; the case page's
"request" card now says how the review came to exist (live, or a replay of
a past morning) instead of echoing a question nobody typed.

Backend counterpart: sm2/custom-apps/denials-investigator/09_one_front_door.sql.
