buildSavePayload matched the active page by page.id === activePageId,
but activePageId defaults to the hardcoded 'home' and load() never
updated it. Deleting the original Home page (its replacement gets id
page_<ts>), reloading, editing, and saving would then match no page --
the live edit only reached the legacy top-level craft_state, while the
authoritative pages[]/pages_craft_state[0] for index.html fell back to
stale state.
Belt-and-suspenders fix:
- buildSavePayload now falls back to pages[0] as the effective active
page when a real page is active but activePageId matches nothing.
- useWhpApi's load() now points activePageId at the freshly restored
first page via a new PageContext setActivePageIdDirect setter
(bookkeeping only -- no re-serialize/deserialize), so activePageId
stays valid after every load.
