feat(fireworks): add glm-5.1, kimi-k2.6 and deepseek-v4-pro models (#198) (#231)

* feat(fireworks): add glm-5.1, kimi-k2.6 and deepseek-v4-pro models (#198)

Adds the three models requested in #198 to the Fireworks provider:
- accounts/fireworks/models/glm-5p1
- accounts/fireworks/models/kimi-k2p6
- accounts/fireworks/models/deepseek-v4-pro

Metadata mirrors the closest existing sibling in each family (glm-4p7,
kimi-k2p5, deepseek-v3p2). Adds a parameterized test asserting the new
models are exposed and selectable.

* fix(fireworks): correct context window and pricing for deepseek-v4-pro, glm-5.1, kimi-k2.6 (#198)

* Update src/api/providers/__tests__/fireworks.spec.ts
