🧵 refactor: Migrate Endpoint Initialization to TypeScript (#10794)

* refactor: move endpoint initialization methods to typescript

* refactor: move agent init to packages/api

- Introduced `initialize.ts` for agent initialization, including file processing and tool loading.
- Updated `resources.ts` to allow optional appConfig parameter.
- Enhanced endpoint configuration handling in various initialization files to support model parameters.
- Added new artifacts and prompts for React component generation.
- Refactored existing code to improve type safety and maintainability.

* refactor: streamline endpoint initialization and enhance type safety

- Updated initialization functions across various endpoints to use a consistent request structure, replacing `unknown` types with `ServerResponse`.
- Simplified request handling by directly extracting keys from the request body.
- Improved type safety by ensuring user IDs are safely accessed with optional chaining.
- Removed unnecessary parameters and streamlined model options handling for better clarity and maintainability.

* refactor: moved ModelService and extractBaseURL to packages/api

- Added comprehensive tests for the models fetching functionality, covering scenarios for OpenAI, Anthropic, Google, and Ollama models.
- Updated existing endpoint index to include the new models module.
- Enhanced utility functions for URL extraction and model data processing.
- Improved type safety and error handling across the models fetching logic.

* refactor: consolidate utility functions and remove unused files

- Merged `deriveBaseURL` and `extractBaseURL` into the `@librechat/api` module for better organization.
- Removed redundant utility files and their associated tests to streamline the codebase.
- Updated imports across various client files to utilize the new consolidated functions.
- Enhanced overall maintainability by reducing the number of utility modules.

* refactor: replace ModelService references with direct imports from @librechat/api and remove ModelService file

* refactor: move encrypt/decrypt methods and key db methods to data-schemas, use `getProviderConfig` from `@librechat/api`

* chore: remove unused 'res' from options in AgentClient

* refactor: file model imports and methods

- Updated imports in various controllers and services to use the unified file model from '~/models' instead of '~/models/File'.
- Consolidated file-related methods into a new file methods module in the data-schemas package.
- Added comprehensive tests for file methods including creation, retrieval, updating, and deletion.
- Enhanced the initializeAgent function to accept dependency injection for file-related methods.
- Improved error handling and logging in file methods.

* refactor: streamline database method references in agent initialization

* refactor: enhance file method tests and update type references to IMongoFile

* refactor: consolidate database method imports in agent client and initialization

* chore: remove redundant import of initializeAgent from @librechat/api

* refactor: move checkUserKeyExpiry utility to @librechat/api and update references across endpoints

* refactor: move updateUserPlugins logic to user.ts and simplify UserController

* refactor: update imports for user key management and remove UserService

* refactor: remove unused Anthropics and Bedrock endpoint files and clean up imports

* refactor: consolidate and update encryption imports across various files to use @librechat/data-schemas

* chore: update file model mock to use unified import from '~/models'

* chore: import order

* refactor: remove migrated to TS agent.js file and its associated logic from the endpoints

* chore: add reusable function to extract imports from source code in unused-packages workflow

* chore: enhance unused-packages workflow to include @librechat/api dependencies and improve dependency extraction

* chore: improve dependency extraction in unused-packages workflow with enhanced error handling and debugging output

* chore: add detailed debugging output to unused-packages workflow for better visibility into unused dependencies and exclusion lists

* chore: refine subpath handling in unused-packages workflow to correctly process scoped and non-scoped package imports

* chore: clean up unused debug output in unused-packages workflow and reorganize type imports in initialize.ts
