Research direction

First, review issues #617 and #411 for detailed requirements. Examine the user model (likely in redash/models/user.py) and the API endpoints for user settings (e.g., redash/api/settings.py). Understand current date/time handling in both backend and frontend. Propose a solution to add configurable date/time format and timezone fields to the user profile, update the API to return and accept these settings, and ensure they are applied consistently across the application.
