Slice-1 part B of the chatelet guest booking UI (aiolabs/webapp #141).
- ChateletApiService: plain HTTP wrapper (events TicketApiService pattern) →
chatelet's public guest endpoints (/public/rooms, /availability). Unauth by
default; swaps HTTP→kind-21000 RPC once aiolabs/lnbits#64 lands, no view change.
- useChatelet composable + pinia store (DI via tryInjectService, never direct import).
- Views: ChateletPage (room grid) + ChateletDetailPage (details + date-range
availability check with sats/fiat quote; Book button stubbed for slice 2).
- SERVICE_TOKENS.CHATELET_API.
