feat: Update module icon and cleanup old icon files

**Changes:**
- Updated module icon: icon5.png → icon.png
- Updated menu web_icon reference in takaful_menus_actions.xml
- Removed old unused icon files (icon2.png, icon3.png, icon4.png, icon5.png, logo.png)
- Updated icon.png with new design

**Files:**
- Modified: odex25_ensan/odex_takaful/static/description/icon.png
- Modified: odex25_ensan/odex_takaful/views/takaful_menus_actions.xml
- Deleted: icon2.png, icon3.png, icon4.png, icon5.png, logo.png

This ensures the new module icon appears correctly after upgrade.
