fix(wifi): has_style_class crash, panel refresh, other networks

- Replace Svg.has_style_class (nonexistent) with _anim_state flag
- Add on_show handler to trigger scan+refresh when wifi widget mapped
- Fix other_networks snap_to_size when section visible with children
- Add destroyed widget guards on connection callbacks
