chore(iris-mpc-store): Try fetching missing serial ids as last resort

[wojciechsromek]

This pull request introduces a new method to stream iris records by explicit serial IDs and integrates it into the database loader for improved recovery of missing records. It also adds comprehensive tests for the new streaming method and enhances error handling and logging when recovering missing data.

New streaming method for irises by ID:

• Added Store::stream_irises_by_ids, allowing efficient streaming of iris records by a list of explicit serial IDs, with missing IDs simply skipped rather than causing an error.

Database loader improvements:

• Integrated the new streaming method into the loader (load_iris_db_internal), enabling a final recovery step that fetches missing records by their IDs, with chunking and a configurable cap to avoid large queries. [1] [2] [3] [4]

Testing and validation:

• Added a dedicated test (test_stream_irises_by_ids) to verify correct results, handling of missing IDs, and empty input for the new streaming method.

Code organization:

• Improved imports and chunking logic in the loader to support the new streaming approach. [1] [2]
