fix: zoom reset on drag and IndexedDB version conflict

- Fix zoom resetting when dragging items (#775): removed useEffect that
  called load() on every autosave-triggered chartXML change, which reset
  the viewport. Moved diagram restore logic to onDrawioLoad where it
  only fires on remount.

- Fix IndexedDB VersionError: template-storage.ts shared the same DB
  name as session-storage.ts but at version 2, causing session storage
  to fail with "requested version (1) < existing version (2)". Give
  templates their own DB ("next-ai-drawio-templates").
