fix: resolve all Cypress TypeScript errors

- Add missing `export {}` to 7 spec files to prevent global scope
  variable redeclaration conflicts (NS, INSTANCE, apiHeaders)
- Fix Cypress.Commands.overwrite visit signature for Cypress 15+
- Fix waitForDeleted return type mismatch (Chainable<Response> vs void)
- Fix HTMLBodyElement cast in runs-filter-and-sort
- Add skipLibCheck to cypress/tsconfig.json for Cypress internal stubs
