Walkthrough

This PR adds support for the Kimi K2.7 Code model from Fireworks by extending the FireworksModelId union type, registering the model's configuration with pricing and context window details, and adding a corresponding test case to verify its properties.

"accounts/fireworks/models/kimi-k2p7-code": change inputPrice from 0.95 to 1.20,
change cacheReadsPrice from 0.19 to 0.60, and change outputPrice from 4.0 to
1.20 so the input/output/cache read rates match the official Fireworks rates

Thanks for adding the model, has some questions about the model params.

[p12tic]

@edelauna Thanks for review, I've addressed your comments.

[p12tic]

@edelauna I think this PR is good to go. Previously some unrelated flaky tests were failing, I just rebased and pushed the same code again.

[edelauna]

Thanks for your patience, yeah we're dealing with some flakey tests on account of upgrading to vitest 4
