- EventForm: check event?.id instead of event to decide PUT vs POST,
fixes "unable to parse string as integer" when creating from template
- TemplateForm: add LocationPicker for setting location on templates
- docker-compose: set TZ=Australia/Perth on backend and db containers
so datetime.now() and PostgreSQL NOW() return local time
