Audited all proxy()/useSnapshot() usage against the v1→v2 migration

## Summary by CodeRabbit
* **Chores**
* Updated the Valtio dependency to a newer version for improved
compatibility.
* **Bug Fixes**
* Improved AI assistant persistence in IndexedDB so chat sessions
reliably save (while keeping only the most recent 20 messages per chat).
* Hardened tabs restoration from storage to fall back to fresh defaults
when data is missing, invalid, or fails validation.
* **Refactor**
* Switched multiple studio panels to use fresh initial-state factories
for initialization and reset reliability.
* Updated advisor state so the derived notification filter count is no
longer exposed.
