Handle Ombi API object-format requestedUser field

The Ombi API returns requestedUser as an OmbiUser object instead of a string.
Add extractRequestedUser helper to extract username from various fields
(alias, userAlias, userName, normalizedUserName) with fallback to legacy string format.
Update client and server routes to use the helper for consistent username extraction.
