refactor: Format code and simplify widget constructors

This commit applies extensive code formatting across the project, primarily by converting multi-line widget and list declarations into single, chained statements. This improves code conciseness and readability.

Key changes include:
- Simplified widget constructor calls and list initializations by removing unnecessary line breaks.
- Refactored `column` and `row` extensions to be more compact.
- Updated `json_serializable` generated files (`.g.dart`) to use the new concise conditional syntax for JSON serialization.
- Removed an unused image asset directory (`assets/img/`).
- Added a build and format command to `README.md`.
