Added feature (orientation= 'both') and fixed padding issues

[Trucee]

✨ Added Feature: orientation="both"

Summary

Added support for orientation="both" to allow simultaneous horizontal and vertical scrolling.

Previously, widgets only supported:

• "vertical"
• "horizontal"

Now users can use:

orientation="both"

to enable scrolling in both directions.

---

Example Usage

scrollable_frame = customtkinter.CTkScrollableFrame(
    master=app,
    orientation="both"
)
scrollable_frame.pack()

This allows content larger than the container to scroll both vertically and horizontally.

---

Behavior

• "vertical" → vertical scrollbar only
• "horizontal" → horizontal scrollbar only
• "both" → both scrollbars appear when needed

Backward compatibility is preserved.
Existing code using "vertical" or "horizontal" works unchanged.

---

🛠 Fix: Border_width

Issue

when user increase Border_width empty space between label and canvas increase automatically.

Combine:

✅ Why This Improvement Is Useful

• Enables more flexible scrollable layouts
• Fixes inconsistency in border_width
• Maintains full backward compatibility

Test script

import customtkinter as ctk

root = ctk.CTk()
root.geometry("1400x550")
root.title('Scroll Frame test')

vertical_sfrm = ctk.CTkScrollableFrame(root, orientation="vertical", label_text='Vertical', border_width=100, border_color='orange',
                                       scrollbar_fg_color='green',
                                       scrollbar_button_color='yellow',
                                       scrollbar_button_hover_color='blue')
vertical_sfrm.pack(side='left', padx=(20, 0))

horizontal_sfrm = ctk.CTkScrollableFrame(root, orientation="horizontal", label_text='Horizontal', border_width=100, border_color='orange', scrollbar_fg_color='green')
horizontal_sfrm.pack(side='left', padx=(20, 0))

both_sfrm = ctk.CTkScrollableFrame(root, orientation="both", label_text='Both Side', border_width=100, border_color='orange', scrollbar_fg_color='green')
both_sfrm.pack(side='left', padx=(20, 0))

grid = 10
for row in range(grid):
    row_frm = ctk.CTkFrame(vertical_sfrm)
    row_frm.pack()
    for col in range(grid):
        label = ctk.CTkLabel(row_frm, text=f"label no: {row}x{col}.")
        label.pack(side='left')

    row_frm.pack()
    for col in range(grid):
        label = ctk.CTkLabel(row_frm, text=f"label no: {row}x{col}.")
        label.pack(side='left')


for row in range(grid):
    row_frm = ctk.CTkFrame(both_sfrm)
    row_frm.pack()
    for col in range(grid):

        label.pack(side='left')

Hi,
I saw your PR, and it is very similar to #2361. Moreover, I've spent a little time implementing the same thing myself, but ultimately, I've decided to postpone it because it was quite impactful.

At the moment, I'm waiting myself for the original owner of the repository to merge all changes I've made from the Develop branch to the main one. I intend to add the proposed feature in one way or another, but I can't promise when it will happen.
