Fix SpotBugs warnings: Implement proper hashCode and equals for core classes

- Implemented consistent `hashCode()` and `equals()` for:
  - `Geofence`: uses id, location, radius, expiration.
  - `PropertyBase`: uses name.
  - `Font`: uses native font or attributes.
  - `Border` / `CSSBorder` / `RoundBorder`: uses fields or identity where appropriate.
  - `Style`: manual hash calculation for primitive arrays (margin/padding) to avoid missing Arrays utility in CLDC.
  - `TarEntry`: added `equals(Object)` override and `hashCode` based on header name.
  - `Transform`: uses type and matrix values.
  - `ImageDownloadService`: uses cacheId.
  - `BoxLayout`: added `align` to equals/hashCode to fix layout update issues.
  - `BorderLayout`, `FlowLayout`, `GridLayout`, `TableLayout`: uses configuration fields.
- Fixed `BoxLayout` equality check to include alignment, resolving layout update regression.
- Manual array hashing in `Style` ensures CLDC 1.1 compatibility.
