fix(booth): asks were invisible in a booth serving its own index.html

A custom index.html is returned verbatim, so booth.html's asks panel never
rendered there — a valid ask (emmie-anchor/anchor.ask.json) was listed by the
CLI and shown nowhere, with nothing to say so.

- panel extracted to _asks.html; new GET /b/<name>/asks standalone page
- verbatim pages get an amber '? N open asks' chip beside the back chip
- POST /answer honours back=asks so answering returns to that page
- single-question asks now keep an optional 'title' (was silently dropped)
- README + routes table; 8 regression tests; v0.1.12
