Misaka Server f715cb97e3 refactor: implement UI code optimization and refactoring
This commit implements the comprehensive UI code refactoring plan to improve
code quality, reduce duplication, and enhance maintainability.

Phase 1: High Priority Improvements
- Create BaseDialog class to eliminate window centering code duplication
  across ProgressDialog, DeleteProgressWindow, LoginDialog, and
  UserSelectionDialog (~30 lines of duplicate code removed)
- Unify log color configuration with LogTheme class in gui/log_config.py
- Create permission check decorators (@require_admin, @require_permission,
  @require_user_type, @handle_errors)
- Update all dialog classes to use unified patterns

Phase 2: Architecture Improvements
- Create input validation framework (ValidationResult, Validator,
  ValidatedWidget classes)
- Implement StateManager with observer pattern for component state sharing
- Create unified ErrorHandler for consistent error handling
- Extract CheckboxTreeview into reusable component

New Modules:
- gui/widgets/base_dialog.py - Base dialog class with modal setup and centering
- gui/utils/decorators.py - Permission and error handling decorators
- gui/utils/error_handler.py - Unified error handling with user-friendly messages
- gui/utils/state_manager.py - State management with observer pattern
- gui/utils/validators.py - Input validation framework
- gui/material_validation/checkbox_treeview.py - Reusable checkbox table

Modified Files:
- gui/log_config.py - Added LogTheme class for centralized styling
- gui/widgets/log_text.py - Use LogTheme.COLORS
- gui/widgets/progress_dialog.py - Inherit from BaseDialog
- gui/widgets/delete_progress_window.py - Inherit from BaseDialog, use LogTheme
- gui/widgets/__init__.py - Add new exports, optional imports
- gui/login_dialog.py - Use unified centering pattern
- gui/user_selection_dialog.py - Use unified centering pattern
- gui/material_validation_tab.py - Import CheckboxTreeview from new module

Benefits:
- Reduced code duplication by ~200 lines
- Improved maintainability through centralized configuration
- Better abstraction with 5 new reusable base classes
- Enhanced type safety with type hints
- Future-proof theming support via LogTheme
