fix: custom handler for fetching requesty models

[requesty-JohnCosta27]

Closes: #10263

Description

Creates 2 custom events (with the same pattern as other provides that need base URL + API key to fetch models).

• the first event is for actually refreshing the models (clicking the Refresh models button)
• the second event is to communicate with the Requesty web view component and display the correct models. (Again, a very similar pattern to other providers).

Test Procedure

• Select Requesty as your provider
• See the full models list
• Go to https://app.requesty.ai and in the Admin Panel, change the approved models list.
• Go back to RooCode
• Hit refresh models

You should now see an updated list of models.

We recently merged some changes to be able to pull models from the API on demand and fully authenticated, I opened this PR #10273 to leverage that new functionality to fix the issue with the Requesty button.

Thank you for working on this PR and for showing us how to fix it properly.
