PRICE-01 round 2: the token on no page, fixed-tariff note, token length, F3 words, test gaps

F1: every password option is shown as ******** (set) or empty in /config/model
(options, running, ui) and in a stale refusal; the classic page draws it as a
password field; a save or validate that sends ******** or nothing keeps the
stored value. F2: a static_profile beside price_service is said once at start
(notification and log), not refused. F3 (owner, 2026-10-14): the no-price row,
Home line and notification only while maintenance_enabled is on. F4: tests for
the reviewer's R01 and R10. F5: price_service_token must be 16+ characters.
