Fix CTkLabel image warning and CTkEntry state access in CustomTkinter UI

[mukeshdhadhariya]

This PR resolves issue #22

1. CTkLabel Image Warning

   • Problem: Passing PIL.ImageTk.PhotoImage to CTkLabel triggers a warning:
     "Given image is not CTkImage but <class 'PIL.ImageTk.PhotoImage'>."
   • Cause: CTkLabel expects a CTkImage for proper rendering and high-DPI support.
   • Fix: Replaced ImageTk.PhotoImage with customtkinter.CTkImage, ensuring proper scaling and eliminating the warning.

2. TclError for CTkEntry State

   • Problem: Accessing entry state via receiver_entry['state'] raises _tkinter.TclError: unknown option "-state".
   • Cause: CTkEntry does not support dictionary-style access for widget options like normal Tkinter widgets.
   • Fix: Replaced receiver_entry['state'] with receiver_entry.cget("state") for reading and receiver_entry.configure(state="...") for writing. This aligns with CustomTkinter's API and prevents runtime errors.
