[front] - refacto: NewDialog wave 4 (#9914)

* [front] - refactor: migrate dialog components to new design system

 - Replaced various Dialog components across multiple setup components with the NewDialog system from @dust-tt/sparkle.
 - Removed unused state hooks and related functions that handled the dialog open/close states.
 - Streamlined the import of React to avoid importing specific named exports and used the base React import with destructuring for hooks.
 - Cleaned up the codebase by removing commented-out lines and unnecessary eslint-disable comments.

* [front] - refactor: streamline dialog descriptions for various API setups

 - Removed redundant wrapper divs and merged paragraphs for brevity in API setup descriptions
 - Simplified layout by removing unnecessary flex gap in dialog container elements

* [front/components/providers] - feature: add universal ProviderSetup component for service configuration

 - Introduce a new general ProviderSetup component to handle configuration of different service providers
 - Refactor existing provider setup pages to use the new universal component, reducing redundancy
 - Update provider setup flow to fetch and mutate SWR data for real-time UI updates
 - Implement state management to handle provider testing, enabling, disabling, and state transitions

[front/pages/w/[wId]/developers/providers] - refactor: integrate universal ProviderSetup into providers page

 - Replace individual provider setup components with the new universal ProviderSetup component

 - Enable setup and editing of both model and service providers through the unified interface
 - Streamline configuration setup process for various service providers with a consistent UI/UX approach

* [misc] - refactor: remove various AI provider setup components

 - Deleted setup components for Anthropic, Azure OpenAI, BrowserlessAPI, Deepseek, Google AI Studio, Mistral AI, OpenAI, SerpAPI, Serper, and TogetherAI from the project
 - It seems like a consolidation or deprecation of AI provider integrations in favor of a streamlined or updated approach

* [front] - refactor: update import statement in ProviderSetup component

 - Modified React import to only import types where necessary for cleaner code organization

* [providers] - refactor: centralize provider configurations

 - Extract provider configurations for models and services into a central location for better management and reusability
