Blocked msg for user and otp should not sent to bloked user

[walmadhagi]

Description

This PR separates the error messaging for blocked users from the recovery flow. Previously, blocked users were receiving the same messaging as users in the recovery flow, which could be confusing and potentially insecure.

Changes

• Created distinct error handling for blocked user accounts
• Removed recovery code generation for blocked users
• Updated error messages to provide clearer guidance for blocked accounts

Security Impact

This change improves security by:

• Preventing recovery codes from being sent to blocked accounts
• Providing clear messaging that directs blocked users to contact system administrators
• Reducing potential confusion between account recovery and account blocking states
