docs: note callbacks=false and declare-time checks for dependent=

[bpamiri]

This follows up #4394 in the consumer models.md (and its wheels new template copy). One line in the dependent= section:

• callbacks=false: delete(callbacks=false) on the parent now skips the dependents' callbacks too (model/associations.cfm passes callbacks to every dependent call).
• Invalid values: an unsupported dependent value throws Wheels.InvalidArgument when the association is declared ($validateDependent), not on the first delete.

tools/build/scripts/ship-consumer-docs.sh check passes, and the template copy is identical.

Review: head 2030aee. APPROVE (docs), with one LOW.

• callbacks=false. It matches fix(model): dependent deletes follow callbacks = false; check dependent when declared #4394 (32b1bdd): $deleteDependents() forwards callbacks in all four dependent= branches, so the parent's delete(callbacks=false) skips the children's callbacks.
• Declaration check. It matches too: hasMany() and hasOne() call $validateDependent() (associations.cfm:75,132), which throws Wheels.InvalidArgument for anything except delete, deleteAll, remove, removeAll or false.
• Both .ai/models.md copies are byte-identical. The line sits in the dependent= section.

LOW: "surfaces at app start". Wheels doesn't load models at application start (onapplicationstart.cfc has no eager model loading). A model's config(), and so the hasMany / hasOne declaration, runs the first time the model is used. Suggest: "...throws Wheels.InvalidArgument when the association is declared (the first time the model loads), not on the first delete."

The final follows PR CI (plus the LOW, if you take it).

FINAL: APPROVE (recorded after merge). Head c8814f1. Docs only: the dependent= line in both .ai/models.md copies (identical), with the LOW fixed ("the first time the model loads"). PR CI: 16 pass, 0 fail, 0 pending, 2 skipping.
