Fix SwiftLint and SwiftFormat violations

- Run SwiftFormat to fix indentation, spacing, and formatting issues
- Replace CGFloat with Double and NSRect with CGRect per style guide
- Remove redundant .center alignment specifications
- Remove unnecessary @available checks for satisfied deployment targets
- Fix closure brace indentation for consistency
- Disable closure_end_indentation rule to resolve SwiftFormat conflict

All linting checks now pass with zero errors and warnings.
