fix: Call recording filter, status sharing FileProvider, anti-revoke group chats, and DB downgrade handling

[mubashardev]

Summary

This PR brings critical fixes on top of the latest upstream changes (WA 2.26.7.xx support, folder selection, AboutActivity updates).

Fixed

• Call recording filter (whitelist/blacklist) now works correctly
• Call recording on loudspeaker now captures both sides of the conversation
• Status download button now shows consistently
• Sharing someone else's status now correctly carries the media to the composer
• Anti-revoke now works in group chats

Improvements

• Status sharing: Uses FileProvider for Android 7+ compatibility instead of direct file URIs
• Database: Added downgrade handling for deleted messages store to prevent crashes on version rollback
• Call recording: shouldRecord() check now correctly filters calls based on whitelist/blacklist/mode settings before starting recording

Notes

• Rebased on top of latest upstream master (includes WA 2.26.7.xx support)
• Build verified ✅
