0.3.0 design: owner decisions Q1-Q7; CUSTOM banner size, native template fonts, banner demo ids

- Per-ad impression listeners plus a capped (100) queue flushed on the first impressionData listener.
- Android adaptive width unit is dp (SDK bytecode).
- Adaptive banners without a fixed width are recreated on safe-area width changes.
- BannerSize gains CUSTOM with customSize { width, height }.
- NativeAdTemplateStyle gains titleFont / bodyFont / callToActionFont ({ family, size }).
- LEVELPLAY_DEMO gains the banner ad unit ids of Unity's sample apps.
- Capacitor 7 targeted for 0.3.0 (verified in a later phase).
