[PB-6484] feature/Live photo support in Photos

[CandelR]

Add Live Photo support: upload both components (photo and video), pair them by naming convention, and reconstruct a real Live Photo on save to gallery.

Summary

• PHAssetExportModule.swift + .m: two new native methods. exportLivePhotoComponents extracts the photo and paired video as raw resource bytes viaPHAssetResourceManager.writeData. saveLivePhoto reconstructs a real Live Photo in the camera roll using PHAssetCreationRequest.addResource.

• LivePhotoNativeModule.ts: typed TS wrapper for both native methods.

• PhotoUploadService: Live Photo assets upload both components. The photo component is uploaded first from the native temp export. The paired video follows. Both temps are cleaned up in finally. Return shape changed from Promise<string> to Promise<{ photoUuid: string; pairedVideoUuid?: string }>. If the video upload fails, the photo is still marked synced and the video is retried in the next cycle.

• PhotoCloudBrowser: fetchMonthFromFolder now runs two passes per day folder, buildPlainNameIndex indexes all plain names first, then buildCloudAssetEntries resolves Live Photo pairing without ordering dependency. Orphan .livephoto.mov files are treated as normal videos.

• cloud_asset schema: new columns is_live_photo, live_photo_role, paired_remote_file_id. Paired video rows are stored but filtered out of the timeline .

• PhotoActionsService: saveToDevice branches on isLivePhoto, downloads both components via PhotoAssetFetchService.fetchLivePhotoComponents and calls saveLivePhotoToLibrary. Falls back to photo-only save if the video download or native call fails.

• PhotoItem: LIVE badge in the top-left corner, mirroring the VideoBadge pattern.

• Android unaffected: isLivePhotoAsset always returns false, no native code runs.
