DEICH-6411 - Fixed debug config and coding error
fromStartTime and toStartTime was overwritten by the string representation of fromEndTime and toEndTime. go 1.19 upgrade done. Fixed debug Dockerfile. Added path to assets as env variable.
DEICH-6411 - TK - using start time for date sorting
This way events on the same day show up in correct order. Otherwise, the order within a day is random.
