fix(import): normalize mixed-case slugs before chunk upsert (#430)

putPage lowercases slugs via validateSlug, but upsertChunks queried
pages by the caller's raw slug — so a mixed-case slug through
importFromContent created the page row, then failed the chunk upsert
with 'Page not found' and rolled back the whole import.

Normalize via validateSlug at importFromContent entry and inside
_upsertChunksOnce on BOTH engines (postgres + pglite parity).

Takeover of #855, rebased onto current master shapes (batchRetry
wrapper / _upsertChunksOnce, rewritten importFromContent opts block).
