🐛 fix: Correct Model Parameters Merging and Panel UI

[danny-avila]

Summary

I fixed issues with model parameter merging in agent initialization and corrected form field watching in the Model Panel. I also added a reset button for model parameters.

Addresses concern raised by

• Refactored agent initialization to correctly merge model_parameters with existing endpoint options.
• Fixed the Model Panel by switching from watch to useWatch in react-hook-form to observe the correct form fields.
• Added a reset button to the Model Panel to reset model parameters to their default values.
• Updated localization strings for the reset button label.

Change Type

• Bug fix (non-breaking change which fixes an issue)

Testing

I tested the changes by:

• Creating new agents and verifying that model parameters are correctly merged during initialization.
• Checking that the Model Panel now watches and updates the correct form fields.
• Using the reset button to ensure it resets model parameters to their default values without issues.
