fix(provider): fix v4 spec to not use shared v3 types

[felixarntz]

Background

The v4 language model spec types were incorrectly importing and using shared v3 types (SharedV3ProviderOptions, SharedV3ProviderMetadata, SharedV3Headers, SharedV3Warning) instead of their v4 equivalents. This meant the v4 spec was not self-contained and depended on v3 shared types.

Initially pointed out by @lgrammel in #13352 (comment).

Summary

Updated all v4 language model spec files to import from shared/v4 instead of shared/v3, using the correct SharedV4* types throughout.

Manual Verification

N/A — type-only change, verified by successful build/type-check.

@aayush-kapoor @gr2m The CI failure here is unrelated to these changes, likely occurring due to the addition of Node 24 in CI, see #13358. I believe it's a test instability, so maybe that's why it worked upon merge of that PR, but now it's causing failures.

See #13483
