Prism 1.5.0-1 security test build 3.

Behavioral target:
- Floating button / trigger invokes the native Prism screenshot flow.
- Native screenshot capture and editor presentation are retained.
- Copy, Pin, Float and related editor tools remain visible and use their original callbacks.
- Screenshot triggers do not redirect to Preferences.

Security-test changes:
- Shared direct/operation authorization success paths.
- Shared feature entitlement helper returns authorized on both completion paths.
- Capture-manager license/ticket preflight final result forced authorized.
- Secondary editor/tool capability preflight final result forced authorized.
- SXEditorViewController allowsFeature final result forced authorized.
- Preferences automatic verification suppressed.

Capture implementation, image creation, crop/selection UI, editor construction, toolbar construction, Copy/Pin/Float callbacks, OCR, translation, Control Center and floating-button implementations remain otherwise unchanged.
