Unify CI and justfile: all workflows call just recipes

- justfile: extract ios_scheme/ios_sim/ios_spm/runner_temp variables; add
  ios-resolve (SPM dep cache), ios-archive, ios-export recipes; pipe xcodebuild
  through xcpretty with raw fallback in ios-build/ios-test
- ios.yaml: replace raw xcodebuild calls with just ios-build / just ios-test;
  install just via brew; uncommented archive job stub now calls just ios-archive
  && just ios-export; add justfile to path trigger
- ci-scraper.yaml: install just via extractions/setup-just@v2; use just lint /
  just test; fix upload-artifact v3 -> v4; add justfile to path trigger
- ci-ui.yaml: install just; use just ui-install / just ui-check / just ui-build;
  add justfile to path trigger
