Terminal errors after deleting chat: message not removed. Chat "ccc" still visible. KAIChat 0.33, KDE Plasma 6.4.2.

SUMMARY
Chat appears to be deleted but reappears after restarting KAIChat

STEPS TO REPRODUCE
1. Open KAIChat
2. Right-click on a conversation in the list
3. Select "Delete"
4. Observe that the chat disappears from the UI
5. Restart the application

OBSERVED RESULT
The chat seems to be deleted at first, but it reappears after restarting the application.

EXPECTED RESULT
The selected chat should be permanently deleted and not come back after restart.

SOFTWARE/OS VERSIONS
Operating System: CachyOS (Arch-based)
KDE Plasma Version: 6.4.2
KDE Frameworks Version: 6.4.2
Qt Version: 6.9.1
KAIChat Version: 0.33 (built from source, master branch)

ADDITIONAL INFORMATION
I launched KAIChat via terminal to investigate the issue. When deleting a chat, the following messages appear:

org.kde.kf.textautogeneratetext.database: Filename doesn't exist: "/home/simone/.local/share/kaichat/ai-database/messages/..."
org.kde.kf.textautogeneratetext.database: The assumption was wrong, deleteMessage was called before addMessage
qt.sql.qsqldatabase: QSqlDatabasePrivate::removeDatabase: connection ... is still in use, all queries will cease to work.

It appears that deleteMessage() is being called before addMessage(), meaning the deletion is not correctly persisted in the database. This results in the conversation being visually removed only temporarily and returning after a restart.

A screenshot of the terminal output is attached.
