🔧 refactor: Centralize Default Agent Capabilities and Better Logging (#7598)

* refactor: Simplify grid column calculation in SourcesGroup component

* refactor: Centralize default agent capabilities and simplify capability assignment

* Edge case: use defined/fallback capabilities for ephemeral agents when the "agents" endpoint is not enabled

* refactor: consolidate gemini 2 vision check

* feat: enhance capability check logging for agents

* chore: update librechat-data-provider version to 0.7.86

* refactor: import default agent capabilities for enhanced capability management

* chore: standardize quotes in error message check for consistency

* fix: improve error logging both client and api-side for mistral ocr upload errors

* ci: update error handling in MistralOCR tests to use specific error message
