🔒 Fix Insecure LocalStorage Usage#6
Conversation
Migrated application state storage for projects and floating panel positions from `localStorage` to IndexedDB using the `idb-keyval` library. Added logic to seamlessly migrate existing user data from `localStorage` over to IndexedDB upon first launch, and safely clean up the legacy `localStorage` keys.

🎯 What: The vulnerability fixed was insecure local storage usage, which could expose sensitive data in a cross-site scripting (XSS) attack and ran into browser quota limitations for large drawing projects.
⚠️ Risk: While the impact is lower in a drawing application, storing potentially large sets of user-generated data or settings in LocalStorage presents a security weakness. It leaves user data vulnerable to theft if an XSS vulnerability were to be introduced elsewhere in the application, and the size limitations often cause unexpected bugs.
🛡️ Solution: Swapped
localStorageusage with IndexedDB via the lightweightidb-keyvaldependency. IndexedDB provides a more secure, modern web storage API that supports asynchronous interaction and handles larger amounts of data without hitting the tight quotas of LocalStorage. I've also implemented backward-compatibility logic to seamlessly migrate user data from LocalStorage to IndexedDB on their next visit, ensuring no data loss.PR created automatically by Jules for task 6470512226870728574 started by @artistso
