Add Preference Page for Managing Floating Windows

[juarezr]

Summary

This PR introduces a new "Windows" settings page in the Forge extension preferences that allows users to view and manage floating window overrides directly from the GUI. This replaces the need to manually edit configuration files and provides a more user-friendly interface for managing which windows should float.

Changes Made

🆕 New Features

• New Windows Settings Page: Added a dedicated preferences page (FloatingPage) for managing floating windows
• Visual Window Management: Users can now see all currently configured floating windows with their titles and window classes
• Remove Functionality: Added ability to remove floating window overrides directly from the preferences interface
• Real-time Updates: Changes made in preferences are immediately reflected in the main extension without requiring restart

🔧 Technical Improvements

• Reload Mechanism: Implemented a signal-based system (window-overrides-reload-trigger) to notify the main extension when floating overrides are modified
• Dangling Pointer Fix: Refactored window override management to prevent dangling pointer issues by properly accessing fresh data from ConfigManager
• Widget Reusability: Added RemoveItemRow widget component for consistent UI patterns

🛠️ Infrastructure Updates

• Makefile Refactoring: Improved test rules and added better error handling for disable command
• Schema Updates: Added new GSettings key for the reload trigger mechanism
• Translation Support: Updated all translation files (es, fr, it, nl, pt_BR, tr) with new strings

Files Changed

Core Functionality

• lib/prefs/floating.js - New floating windows management page
• lib/prefs/widgets.js - Added RemoveItemRow widget component
• lib/extension/window.js - Added reload mechanism and fixed dangling pointers
• prefs.js - Integrated new floating page into preferences

Configuration & Schema

• schemas/org.gnome.shell.extensions.forge.gschema.xml - Added reload trigger setting

Translations

• Updated all .po files with new translatable strings
• Synchronized line numbers across all translation files

Build System

• Makefile - Refactored test rules and improved error handling

How It Works

1. View Floating Windows: The new page displays all windows configured to float, showing both the window title and WM class
2. Remove Overrides: Users can click the remove button next to any floating window to remove it from the floating list
3. Real-time Sync: When changes are made, a timestamp is set in GSettings that triggers the main extension to reload its window overrides
4. Persistent Storage: All changes are saved to the configuration file and persist across extension restarts

Testing

✅ Tested floating window removal functionality
✅ Verified real-time reload mechanism works correctly
✅ Confirmed changes persist across extension restarts
✅ Updated translation files are properly formatted

Looks good. I am not able to test it though
