Enhance Security: Hide Password Input in CLI Login Command

[SevanBadal]

Currently, the box login and register command requires users to input their email and password in a single line (box login <email> <password>). This approach exposes the password in plaintext, which is a security risk. It can be seen in command line history, process lists, and potentially logs, making it vulnerable to unauthorized access.

Proposed Change:

Refactor the box login command to enhance security:

Change Command Structure: Modify the box login command to only require the email as an initial input (box login <email>).
Prompt for Password: After the email is entered, the CLI should prompt the user to enter their password. This prompt should not echo the password back to the screen to ensure it remains hidden.
