Summary

Resolves #992

Improves code interface validation errors when action params are accidentally passed as a keyword list instead of a params map.

Example of the incorrect call shape:

MyApi.create_user(first_name: "Fred")

instead of:

MyApi.create_user(%{first_name: "Fred"})

Previously, Ash raised an unknown options error for :first_name even when it was a valid action input. This PR adds a targeted hint explaining the likely mistake and shows the expected call shape.

Behavior

When unknown options are detected, Ash now checks whether those keys are valid action inputs.

If they are, the validation error includes a helpful hint with the proper function usage. Non-input unknown options continue behaving exactly as before.

Tests

Added regression coverage for:

• create interfaces with keyword-list params
• bang interfaces showing the correct function name
• unknown non-input options not receiving hints
• update interfaces showing the record argument in examples
