Grafana/log-analyser not working after fresh setup with docker on Ubuntu24

[pzystorm]

As complained in this bug #1956 I have now found a solution what needs to be changed:

• it seems the datasource ids are random ids. The current grafana version can handle plaintext names of the datsources
• the datasources were not imported, because ./log-analyser/grafana-provisioning/datasources was not mounted
• after one day I have always reached some max_send_msg_size limit and Grafana could not get data from loki, to the limit has been set from 4mb to 32mb and works now much much better than before
• the otel component has complained about "loglevel: debug" which seems to be some old style format
