docs: Execute notebooks with updated type system

Executed 19 notebooks and saved outputs after removing unsigned types:

How-To:
- model-relationships.ipynb
- read-diagrams.ipynb

Basic Tutorials:
- 01-first-pipeline.ipynb
- 02-schema-design.ipynb
- 03-data-entry.ipynb
- 04-queries.ipynb
- 05-computation.ipynb

Advanced Tutorials:
- custom-codecs.ipynb
- distributed.ipynb
- json-type.ipynb
- sql-comparison.ipynb

Domain Tutorials:
- allen-ccf.ipynb
- calcium-imaging.ipynb
- electrophysiology.ipynb

Example Tutorials:
- blob-detection.ipynb

- hotel-reservations.ipynb
- languages.ipynb
- university.ipynb

Skipped (require object store config):
- 06-object-storage.ipynb
- ephys-with-npy.ipynb

All executed notebooks validate that uint → int type replacements
work correctly with current DataJoint 2.0 implementation.
