* 🗑️ chore: Remove unused Legacy Provider clients and related helpers

* Deleted OpenAIClient and GoogleClient files along with their associated tests.
* Removed references to these clients in the clients index file.
* Cleaned up typedefs by removing the OpenAISpecClient export.
* Updated chat controllers to use the OpenAI SDK directly instead of the removed client classes.

* chore/remove-openapi-specs

* 🗑️ chore: Remove unused mergeSort and misc utility functions

* Deleted mergeSort.js and misc.js files as they are no longer needed.
* Removed references to cleanUpPrimaryKeyValue in messages.js and adjusted related logic.
* Updated mongoMeili.ts to eliminate local implementations of removed functions.

* chore: remove legacy endpoints

* chore: remove all plugins endpoint related code

* chore: remove unused prompt handling code and clean up imports

* Deleted handleInputs.js and instructions.js files as they are no longer needed.
* Removed references to these files in the prompts index.js.
* Updated docker-compose.yml to simplify reverse proxy configuration.

* chore: remove unused LightningIcon import from Icons.tsx

* chore: clean up translation.json by removing deprecated and unused keys

* chore: update Jest configuration and remove unused mock file

    * Simplified the setupFiles array in jest.config.js by removing the fetchEventSource mock.
    * Deleted the fetchEventSource.js mock file as it is no longer needed.

* fix: simplify endpoint type check in Landing and ConversationStarters components

    * Updated the endpoint type check to use strict equality for better clarity and performance.
    * Ensured consistency in the handling of the azureOpenAI endpoint across both components.

* chore: remove unused dependencies from package.json and package-lock.json

* chore: remove legacy EditController, associated routes and imports

* chore: update banResponse logic to refine request handling for banned users

* chore: remove unused validateEndpoint middleware and its references

* chore: remove unused 'res' parameter from initializeClient in multiple endpoint files

* chore: remove unused 'isSmallScreen' prop from BookmarkNav and NewChat components; clean up imports in ArchivedChatsTable and useSetIndexOptions hooks; enhance localization in PromptVersions

* chore: remove unused import of Constants and TMessage from MobileNav; retain only necessary QueryKeys import

* chore: remove unused TResPlugin type and related references; clean up imports in types and schemas
