Update version to 1.0.3

ProfiMaktab v1.0.3 - Fix Sensor Attributes and Thread Safety

🐛 Bugs Fixed

Critical Issues

• Fixed RuntimeError on dispatcher callback: Sensor attributes were not displaying in UI due to async_write_ha_state() being called from non-event-loop thread
• Fixed thread-safety violation: Dispatcher callbacks now use call_soon_threadsafe() to safely update sensor state
• Fixed missing sensor attributes: Attributes (lessons, marks, etc.) now properly display after data fetch from API
• Fixed ProfiMaktabOptionsFlow attribute conflict: Resolved property naming conflict in config flow

Improvements

• Added initial state write in async_added_to_hass() to immediately display sensor data after setup
• Removed excessive DEBUG logging for cleaner Home Assistant logs
• Enhanced error handling in data update process

📊 What's Changed

• Thread-safe dispatcher implementation for sensor updates
• Proper lifecycle management for sensor attributes
• Improved logging for troubleshooting
• Better data synchronization between sensors

✅ Testing

• Sensor attributes now display correctly in UI
• Button "Update ProfiMaktab Data" works without errors
• Data updates propagate correctly across all sensors
• No more event loop thread-safety errors
