Fix: Align dialog buttons to the end and update version

This commit addresses an issue with the alignment of buttons within the `PersianDatePickerDialog` and increments the library version.

**Key Changes:**

- **Dialog Button Alignment:**
    - In `PersianDatePickerDialog.kt`, the `Row` containing the dismiss and confirm buttons now uses `Modifier.fillMaxWidth()` and `horizontalArrangement = Arrangement.End`. This ensures the buttons are aligned to the end (right side in LTR, left side in RTL) of the dialog, consistent with common dialog design patterns.
    - The `Arrangement.spacedBy(DialogButtonsMainAxisSpacing)` was removed as `Arrangement.End` handles the spacing in this context.
- **Version Update:**
    - The library version in `library/build.gradle.kts` has been incremented from `0.0.12-beta1` to `0.0.12-beta2`.
- **Added Screenshots:**
    - New screenshots have been added to the `screenshots` directory:
        - `Screenshot From 2025-10-01 05-47-22.png`
        - `Screenshot From 2025-10-01 05-47-27.png`
        - `Screenshot From 2025-10-01 05-47-37.png`
        - `Screenshot From 2025-10-01 05-47-49.png`

These changes improve the visual consistency of the dialog and prepare for a new beta release.
