Reformatted code across multiple modules, standardizing string quotes, indentation, and spacing. Improved readability by restructuring blocks and aligning object properties consistently. These changes ensure better code maintainability and follow standard conventions. Signed-off-by: Toby Liddicoat <toby@codesure.co.uk>
