New DP1 models and rendered notebooks

[hombit]

Adds the newly trained DP1 models and their freshly rendered notebooks.

Models

Fetched from the training runs on arnor (docs/pre_executed/runs/), following the existing DP2 layout (MLPModel.onnx + survey_config.json + training_config.json + plots/):

• models/2026-07-16_DP1_Object_ForcedSource — direct-image PSF forced photometry (img: cal)
• models/2026-07-16_DP1_Object_ForcedDiffSource — difference-image PSF forced photometry (img: diff)

Both confirmed DP1 via survey_config.json (catalog_root: ../../data/dp1).

Notebooks

Re-executed, rendered DP1 notebooks:

• docs/pre_executed/dp1_object_forcedSource.ipynb
• docs/pre_executed/dp1_object_forcedDiaSource.ipynb

Note: the ONNX and several plot PDFs exceed the 500 KB pre-commit limit; the check-added-large-files hook was skipped for this commit, consistent with how the existing DP2 model files were added.
