🔁 refactor: Capabilities for Tools/File handling for Direct Endpoints (#8253)

* feat: add useAgentCapabilities hook to manage agent capabilities

* refactor: move  agents and endpoints configuration to AgentPanel context provider

* refactor: implement useGetAgentsConfig hook for consolidated agents and endpoints management

* refactor: enhance ToolsDropdown to utilize agent capabilities and streamline dropdown item rendering

* chore: reorder return values in useAgentCapabilities for improved clarity

* refactor: enhance agent capabilities handling in AttachFileMenu and update file handling logic to allow capabilities to be used for non-agents endpoints
