fix: correctly set user agent / fingerprint id on user sessions (#8231)

# Which Problems Are Solved

When we switched to V2 tokens (#7822), the user agent was incorrectly
set for sessions created though the login UI.
Additionally, when calling the ListMyUserSessions from the AuthService,
any session without the fingerprint ID (e.g. created through the session
API) would be listed.

# How the Problems Are Solved

- Use the intended ID of the user agent (fingerprint)
- Ignore empty user agent IDs when listing the user sessions

# Additional Changes

None.

# Additional Context

- relates #7822 
- closes #8213
