🧑‍💻 fix: Agents Config Defaults and Avatar Uploads Across File Strategies (#7814)

* fix: avatar processing across storage services, uniqueness by agent ID, prevent overwriting user avatar

* fix: sanitize file paths in deleteLocalFile function to prevent invalid path errors

* fix: correct spelling of 'agentsEndpointSchema' in agents.js and config.ts

* fix: default app.locals agents configuration setup and add agent endpoint schema default
