[UI] Add Checkbox for Combined Deposit and Delegate Function in Restaking

[AtelyPham]

We need to implement a checkbox for the deposit function that allows users to simultaneously deposit and delegate their funds. The current interface, which presents both options initially, can be confusing for users.

Additionally, the current layout lacks consistency. In the Deposit + Delegate flow, there's an entire container dedicated to operator selection. This seems unnecessary and places undue emphasis on a feature that doesn't require such prominence.

Proposed changes:

1. Add a checkbox labeled "Deposit and Delegate" to the deposit interface.
2. Simplify the operator selection process in the Deposit + Delegate flow.
3. Standardize the user interface across different functions for better consistency.

These modifications will improve user experience by simplifying the process and reducing confusion, while also creating a more cohesive design throughout the platform.
