[Bugfix] Customer-Technician Account Loop:

• Issue: When a user tried to sign in as a customer using an email already associated with a technician account, they were kicked out to the login page.
• Fix: A warning message now appears, preventing this from happening by notifying the user upfront that the email is already linked to a technician account.

[Bugfix] “Post with Same Technician” Flow:

• Issue: The system allowed users to select technicians for non-vetted categories, which shouldn’t be allowed.
• Fix: This flow has been corrected, and technician selection is now restricted to only vetted categories as intended.
