fix: correct test count to verified 1770+ tests, replace SDK methods stat with API endpoints

- Update about page Jest test stat from 775+ to verified 1770+ (confirmed via jest run)
- Replace misleading "39 SDK Methods" with "260+ API Endpoints"
- These numbers are now accurate as of the 77 test suites / 1770 tests run
