fix: Pass selectedOption parameter to performStatusChange function

Fixed scope issue where selectedOption variable was not accessible in
performStatusChange(). Updated function signature to accept selectedOption
as a parameter and updated both call sites to pass it.

Resolves error: "selectedOption is not defined" when changing ticket status.
