refactor: introduce unified contact parsing and display system

Extracts contact information parsing logic into reusable parsers for
both JSContact and vCard formats. Introduces ContactTable component
for consistent contact rendering across both formats, reducing code
duplication and improving maintainability.

- Add contact-parser.ts with parseJSContact() and parseVCard()
- Add ContactTable component for unified contact display
- Refactor JSContactDisplay and VCardDisplay to use new parsers
- Add comprehensive test suite for contact parsers (488 test cases)
- Move WHOIS Server field to DataList in EntitiesSection
- Fix DynamicDate tooltip to avoid duplicate time display
- Standardize import paths to use @ alias
- Update tooltip text for RDAP URL button clarity
