Feat/vertex-claude-support (#7564)

* feat(migrate): add default settings for assistants during migration

- Introduced a new migration step to assign default settings for assistants that lack configuration.
- Default settings include temperature, context count, and other parameters to ensure consistent behavior across the application.

* chore(store): increment version number to 115 for persisted reducer

* feat(vertex-sdk): integrate Anthropic Vertex SDK and add access token retrieval

- Added support for the new `@anthropic-ai/vertex-sdk` in the project.
- Introduced a new IPC channel `VertexAI_GetAccessToken` to retrieve access tokens.
- Implemented `getAccessToken` method in `VertexAIService` to handle service account authentication.
- Updated the `IpcChannel` enum and related IPC handlers to support the new functionality.
- Enhanced the `VertexAPIClient` to utilize the `AnthropicVertexClient` for model handling.
- Refactored existing code to accommodate the integration of the Vertex SDK and improve modularity.

* feat(vertex-ai): enhance VertexAI settings and API host management

- Added a new method to format the API host URL in both AnthropicVertexClient and VertexAPIClient.
- Updated getBaseURL methods to utilize the new formatting logic.
- Enhanced VertexAISettings component to include an input for API host configuration, with help text for user guidance.
- Updated localization files to include new help text for the API host field in multiple languages.

* fix(vertex-sdk): update baseURL handling and patch dependencies

- Refactored baseURL assignment in AnthropicVertexClient to ensure it defaults to undefined when the URL is empty.
- Updated yarn.lock to reflect changes in dependency resolution and checksum for @anthropic-ai/vertex-sdk patch.

* refactor(VertexAISetting): use provider.id rather than provider

* refactor: improve API host formatting in AnthropicVertexClient

- Updated the `formatApiHost` method to streamline host URL handling.
- Introduced a helper function to determine if the original host should be used based on its format.
- Ensured consistent appending of the `/v1/` path for valid API requests.

* fix: handle empty host in AnthropicVertexClient

- Added a check in the `getBaseURL` method to return the host if it is empty, preventing potential errors.
- Included a console log for the base URL to aid in debugging and verification of the URL formatting.

* feat(AnthropicVertexClient): add logging for authentication errors and mock client in tests

- Introduced logging functionality in AnthropicVertexClient to replace console.error with logger service for better error tracking.
- Added mock implementation for AnthropicVertexClient in tests to enhance testing capabilities.
- Updated package.json to include the @aws-sdk/client-s3 dependency.

* feat(tests): add comprehensive tests for client compatibility types

- Introduced a new test file to validate compatibility types for various API clients including OpenAI, Anthropic, Gemini, Aihubmix, NewAPI, and Vertex.
- Implemented mock services to facilitate testing and ensure isolation of client behavior.
- Added tests for both direct API clients and decorator pattern clients, ensuring correct compatibility type returns.
- Enhanced middleware compatibility logic tests to verify correct identification of compatible clients.
