* Keep per-item LATENT session refs when joining mapped outputs
Ordered phases bridge values between phases as remote session refs.
Joining mapped LATENT outputs ran _join_latent_batches on those refs,
which copied the first ref's fields and collapsed every item to item 0.
The next phase then broadcast item 0's latent to all items, so a second
KSampler fed by a mapped first KSampler always refined the first image.
Only merge LATENT values that are real latent mappings; otherwise keep
the ordered list. Log boundary inputs that are broadcast because they
cannot be split instead of dropping the error silently.

* Cap Modal containers at instance_count across parameter-set pools
Modal enforces max_containers per RemoteEngine parameter set. Remote
components without loaders (e.g. SaveImageAdvanced) had an empty
snapshot profile, so they opened a second pool of GPU containers beside
the samplers and doubled the container count past instance_count.
- Stamp the environment's most common loader snapshot profile onto
profile-less Comfy-pool components so they share one container pool.
- Hold one host-side slot per in-flight Modal call per deployment app,
capped at max_containers, so concurrent mapped components share the
configured budget.
- Lower the per-item unsplittable boundary input log to debug.
