fix: support secure capture on One UI 8

[nullptroma]

Fixes screenshots and built-in screen recording for FLAG_SECURE apps on Samsung One UI 8 / Android 16.

• Hooks Samsung WmScreenshotController policy and secure-content capture path.
• Returns false from WindowState.isSecureLocked() so secure layers can also be mirrored by Samsung Screen Recorder.

Tested on Galaxy S25 (SM-S931B), One UI 8.5 / Android 16: screenshots and screen recordings work.

Note: this intentionally disables app-level FLAG_SECURE protection globally.

FLAG_SECURE should not be disabled, as this will break bank app's security detection.

Okay, I’ll try a different approach. And there’s also something specific to Samsung that needs to be tried...

[nullptroma]

Updated the branch with a Samsung-specific approach.

• Restored the original stack-aware hookWindowState, so FLAG_SECURE is preserved during surface creation.
• Added One UI 8 WmScreenshotController handling that bypasses only the FLAG_SECURE failure reason, while preserving Samsung MDM policy denial.
• Added a narrow SystemUI hook for managed-profile screenshots: it clears secureLayer for type == 3 requests but leaves disableCapture unchanged.

The implementation was verified against the matching services.jar, framework.jar, and SystemUI.apk from a Galaxy S25 on One UI 8.5 / Android 16, and tested in both primary and Work Profile.

Screen recording is no longer enabled by this PR

Please upload the JAR files for Samsung system framework and services.

I got this working on my s26 ultra (SM-S948N). The PR as-is didn't work for me. It matches methods by name and parameter count, but the screenshot method on the s26u takes 6 parameters, so it never hooks. My fix was to hook the method with a single boolean parameter (the secure-content-policy flag) instead, and that did the trick. I can share my code if anyone's interested, though all of it done with AI help.

Can this work on temporary root ..(root my galaxy) s24 ultra without bootloop
