fix(models): correct o4-mini pricing under chatOpenAI

[AbdulSamad94]

The o4-mini entry under chatOpenAI in models.json had incorrect pricing values copied from gpt-4o-mini instead of the actual o4-mini pricing.

Impact

• Input cost was 1.5e-7 (gpt-4o-mini price), should be 1.1e-6 (~7.3× higher)
• Output cost was 6e-7 (gpt-4o-mini price), should be 4.4e-6 (~7.3× higher)

This caused cost tracking and billing calculations to vastly underestimate the real cost by roughly 86% when users selected o4-mini.

(Note: The azureChatOpenAI section already had the correct o4-mini pricing, confirming this was an oversight in chatOpenAI.)

Changes

• Updated packages/components/models.json: corrected input_cost and output_cost for o4-mini under chatOpenAI to match the official OpenAI pricing.

Code Review

This pull request updates the pricing configuration for the o4-mini model in packages/components/models.json, increasing both the input and output costs. There are no review comments to address, and I have no feedback to provide.
