Fix streaming support for multi property configurations

Description & motivation

Resolves #254

As noted by @FlorianASchroeder , PR #250 allowed the union of intraday data only for single-property configurations.

This update removes that limitation by leveraging the fact that both daily and intraday event tables start with 'events_'. This means we can use a wildcard operation to query events_* to pull both daily and intraday records. Duplicate records will be deduped as part of the base_ga4__events qualify statement.

As a result, we can remove the intraday source from src_ga4.yml

My concern with this PR is that the qualify statement at the end won't deduplicate in all situations. I am not aware of any event_params that get added when Google processes the GA4 data, but just one field would cause the deduplication to stop working.

I'm also concerned that deduplicating this way will take a lot of unnecessary processing, but I can't think of a better way of doing this.
