fix(notifications): improve error handling (#8994)

# Which Problems Are Solved

While running the latest RC / main, we noticed some errors including
context timeouts and rollback issues.

# How the Problems Are Solved

- The transaction context is passed and used for any event being written
and for handling savepoints to be able to handle context timeouts.
- The user projection is not triggered anymore. This will reduce
unnecessary load and potential timeouts if lot of workers are running.
In case a user would not be projected yet, the request event will log an
error and then be skipped / retried on the next run.
- Additionally, the context is checked if being closed after each event
process.
- `latestRetries` now correctly only returns the latest retry events to
be processed
- Default values for notifications have been changed to run workers less
often, more retry delay, but less transaction duration.
