fix: omit job_asset_name_filters when all job outputs selected (#9684)

## Summary

- When bulk exporting, `job_asset_name_filters` was always sent for
every job, restricting each job to only the assets the user clicked on.
For multi-output jobs, this meant the ZIP only contained 1 asset per job
instead of all outputs.
- Now compares selected asset count per job against `outputCount`
metadata and omits the filter for fully-selected jobs, so the backend
returns all assets.

## Test plan

- [x] Unit tests: all outputs selected → no filter sent
- [x] Unit tests: subset selected → filter sent
- [x] Unit tests: mixed selection → filter only for partial jobs
- [x] Unit tests: multiple fully-selected jobs → no filters
- [x] Typecheck, lint pass
- [ ] Manual: bulk export multi-output jobs in cloud env, verify ZIP
contains all outputs
