Replace unsafe .cast<Map<String, dynamic>>() with .whereType() to
prevent runtime errors when parsing images array.

The .cast() method throws at runtime if list contains non-Map items.
The .whereType() method safely filters out invalid items.

Add unit and widget tests for video functionality:

StreamableService tests (19 test cases):
- Shortcode extraction from various URL formats
- Standard URLs: streamable.com/abc123
- /e/ URLs: streamable.com/e/abc123
- URLs without scheme
- URLs with query parameters
- Video URL fetching with mocked API responses
- Caching behavior validation
- Error handling (404, missing fields, network errors)
- Protocol-relative URL handling

PostCard widget tests:
- Play button display for Streamable videos
- Loading indicator during API calls
- No play button for non-video embeds
- Proper StreamableService injection

All tests passing with proper mocking using http_mock_adapter.
