Organic deployment timeouts on Foundation Catalysts

Some scene deployments can take a long time, well over 2 minutes. When this happens, Cloudflare times out after 2 mins of inactivity. These scenes probably span too many lands and ownership checking takes a lot of time.
Using subgraphs, for a scene of `n` parcels, it could make `3 * n` queries for checking for land ownership, operator permissions and estate. These could probably be either batched or run in parallel.
For the new on-chain validations, batching is already happening, but this still takes more than 2 mins.
We should see how we can do to speed up those queries.

No files or tests are named. Start by locating the scene deployment path and tracing ownership, operator-permission, estate, and on-chain validation queries for multi-land scenes. Measure query counts and latency, then verify that slow deployments no longer hit Cloudflare's two-minute inactivity timeout.
