📂 refactor: Cleanup File Filtering Logic, Improve Validation (#10414)

Browse source 
* feat: add filterFilesByEndpointConfig to filter disabled file processing by provider

* chore: explicit define of endpointFileConfig for better debugging

* refactor: move `normalizeEndpointName` to data-provider as used app-wide

* chore: remove overrideEndpoint from useFileHandling

* refactor: improve endpoint file config selection

* refactor: update filterFilesByEndpointConfig to accept structured parameters and improve endpoint file config handling

* refactor: replace defaultFileConfig with getEndpointFileConfig for improved file configuration handling across components

* test: add comprehensive unit tests for getEndpointFileConfig to validate endpoint configuration handling

* refactor: streamline agent endpoint assignment and improve file filtering logic

* feat: add error handling for disabled file uploads in endpoint configuration

* refactor: update encodeAndFormat functions to accept structured parameters for provider and endpoint

* refactor: streamline requestFiles handling in initializeAgent function

* fix: getEndpointFileConfig partial config merging scenarios

* refactor: enhance mergeWithDefault function to support document-supported providers with comprehensive MIME types

* refactor: user-configured default file config in getEndpointFileConfig

* fix: prevent file handling when endpoint is disabled and file is dragged to chat

* refactor: move `getEndpointField` to `data-provider` and update usage across components and hooks

* fix: prioritize endpointType based on agent.endpoint in file filtering logic

* fix: prioritize agent.endpoint in file filtering logic and remove unnecessary endpointType defaulting
