fix: don't abort make_adata when ontology translation fails

[LiudengZhang]

Summary 📝

make_adata calls translate() to populate the cosmetic conv_* columns with human-readable ontology names. translate() can raise on an id it cannot resolve — notably comma-joined CellxGene terms like self_reported_ethnicity_ontology_term_id = "HANCESTRO:0005,HANCESTRO:0008", which a model legitimately predicts because such labels are in the training vocabulary. When that happens, the entire prediction/embedding run aborts (#49).

Details

1. Wrap the two translate() calls in make_adata so a translation failure emits a warnings.warn and skips the affected conv_* column instead of raising.
2. The actual predictions (pred_* columns) and embeddings are untouched — only the optional human-readable convenience columns are affected.
3. The root cause is also fixed upstream in scdataloader's translate() (fix: handle compound ontology ids in translate() jkobject/scDataLoader#33, which resolves compound ids properly). This scPRINT-side change is defense-in-depth: it keeps make_adata robust regardless of the installed scdataloader version.

Bugfixes 🐛

• make_adata no longer crashes the whole run when an ontology id (e.g. a compound CellxGene ethnicity term) can't be translated.

Checks

• Closes Comma concatenated ontology term ID not in lamindb causes error in translate #49
• Tested Changes — change is a localized try/except around an existing call; verified by inspection (no behaviour change on the success path, only the failure path now degrades gracefully)
• Stakeholder Approval
