perf: improve scalability of session api (#9635)

This pull request improves the scalability of the session API by
enhancing middleware tracing and refining SQL query behavior for user
authentication methods.

# Which Problems Are Solved

- Eventstore subscriptions locked each other during they wrote the
events to the event channels of the subscribers in push.
- `ListUserAuthMethodTypesRequired` query used `Bitmap heap scan` to
join the tables needed.
- The auth and oidc package triggered projections often when data were
read.
- The session API triggered the user projection each time a user was
searched to write the user check command.

# How the Problems Are Solved

- the `sync.Mutex` was replaced with `sync.RWMutex` to allow parallel
read of the map
- The query was refactored to use index scans only
- if the data should already be up-to-date `shouldTriggerBulk` is set to
false
- as the user should already exist for some time the trigger was
removed.

# Additional Changes

- refactoring of `tracing#Span.End` calls

# Additional Context
