♻️ refactor(enclosure): improve section handling and width calculation

- remove unused import 'circle' from primitives
- change isEndSection type to a specific string type for clarity
- add 'hasPort' property to SectionOptions for extended functionality
- modify width calculation to separate constants and adjusted values for end sections
- update geometry calculations to reflect new width adjustments and end section specifications
