OpenAIVideoSora2 Frontend pricing (#5958)

test: update OpenAIVideoSora2 tests to use `size` instead of
`resolution`

Refactored all OpenAIVideoSora2 test cases in useNodePricing.test.ts to
align with
the updated node logic that replaces the `resolution` widget with
`size`.
Adjusted validation, pricing, and error message expectations
accordingly.
