Auto-size widgets and auto place widgets

Feature Request: Intelligent dashboard widget auto-sizing and placement

Summary:
Enable dashboards to automatically size and place newly added widgets within the grid based on widget type and the order they are added. This should help users create dashboards faster while preserving any existing manual widget configurations.

Problem Statement:
Currently, users must manually size and position dashboard widgets when creating a new dashboard or adding multiple widgets. This process can be time-consuming and inconsistent, especially when several widgets are added at once. It also creates unnecessary setup work for users who expect a new dashboard layout to be organized automatically from the start.

Proposed Solution:
Add intelligent auto-sizing and placement logic for widgets when they are added to a dashboard. The system should assign a minimum default size based on widget type and place each widget within the grid according to the order in which it was added. This behavior should apply only to newly added widgets and should not alter any existing widgets that have already been manually sized or positioned by the user.

Benefits:
Reduces the time required to build and configure dashboards. Improves the consistency and usability of new dashboard layouts. Preserves user control by leaving existing manual widget settings unchanged. Creates a more efficient and intuitive dashboard setup experience.
