refactor: rename app from Severed to OpenAppLock

Full rename ahead of App Store submission: project, targets, bundle
identifiers (dev.bchen.Severed -> dev.bchen.OpenAppLock), entitlements
file, app entry point, user-facing onboarding strings, test helpers,
and docs. Verified: all 62 unit tests pass.
