feat(hogql): no_persons poe mode

[mariusandra]

Problem

We want to support personless events.

Changes

Adds a new PoE mode no_persons that just blanks out all person properties and IDs. This doesn't make them null completely, but gives a zero UUID value. So you will see 1 user when any user was active, and 0 users when no users were active.

To enable it locally, modify these lines:

posthog/posthog/hogql/modifiers.py

Lines 23 to 27 in 205376b

	if modifiers.personsOnEventsMode is None:
	if team.person_on_events_v3_querying_enabled:
	modifiers.personsOnEventsMode = PersonsOnEventsMode.v3_enabled
	else:
	modifiers.personsOnEventsMode = team.person_on_events_mode

We might want an empty '{}' for properties instead of the null to not have everything fail, but it's a start.

How did you test this code?

Just locally in the /debug page for now.
