Moves the fee_address/bet_amount_sats config form out of the main test
UI into a dedicated admin.html, served by a GET /admin route
(registered ahead of the StaticFiles mount so it doesn't shadow the
existing GET/PUT /admin/config API). Deliberately not linked from the
test UI in either direction: reachable only by knowing the URL.

Lets an operator load and update fee_address/bet_amount_sats from a
form (using the X-Admin-Token header) instead of curl/Swagger, with
inline status feedback and the same request/response log as the rest
of the page.

Single-page vanilla HTML/JS frontend (register/login, balance,
place bet, withdraw) served by FastAPI at the same origin so it can
exercise the live API without CORS setup. Manual-testing aid only,
not part of the MVP spec.
