fix(#106): [SECURITY] scope recent files and favorites per user

Root cause: localStorage keys 'oxicloud_recent_files' and
'oxicloud_favorites' were global — shared across all users on the same
browser. When user A logged out and user B logged in, user B could see
(and access) user A's recent files and favorites.

Fixes applied:

recent.js:
- Storage key now user-specific: 'oxicloud_recent_files_{username}'
- getStorageKey() derives key from current user in localStorage
- migrateFromLegacyKey() moves data from old global key on init
- Legacy global key is always removed after migration

favorites.js:
- Same pattern: 'oxicloud_favorites_{username}'
- getStorageKey() + migrateFromLegacyKey() added

auth.js (logout):
- Clears user-specific recent and favorites keys before removing
  user data, plus removes any legacy global keys

Bumps service worker cache to v13.
