* Use <number>.<number> format for Google Analytics client ID

With the `ENFORCE_RECOMMENDATIONS` [validation behavior](https://developers.google.com/analytics/devguides/collection/protocol/ga4/validating-events?client_type=firebase#send_events_for_validation), Google Analytics warns about client IDs not in the <number>.<number> format.

This is not an issue in practice - that recommendation is for compatibility with existing client IDs and events are still processed with a client ID in any format. Additionally, the validation is not enabled by default.

However, this PR updates our sample code to use a consistent ID regardless to reduce noise if the validation is enabled. We use a random ID concatenated with a UNIX timestamp to match other GA client libraries.
