Add setting to disable live clipboard updates in preview dialog

Added a new setting "Disable live clipboard update" that prevents the preview
and filename fields from automatically updating when the clipboard changes while
the dialog is open. This allows users to safely edit filenames or copy text to
use as filenames without the dialog being overwritten by new clipboard content.

Changes:
- Added disableLiveClipboardUpdate setting (default: false) to Settings.settings
- Added property accessor in Settings.Designer.cs
- Added menu item to settings context menu in Wizard.Designer.cs
- Added handler menuDisableLiveClipboardUpdate_CheckedChanged in Wizard.cs
- Modified ClipboardChanged in Dialog.cs to check setting and return early if enabled
- Added resource strings str_disable_live_clipboard_update and tooltip

The setting is accessible via the settings menu (gear icon) in the Wizard dialog.
When enabled, clipboard changes are ignored while the preview/rename dialog is open,
preventing the preview and filename fields from being overwritten.
