Surveys: Support event trigger property filters

[adboio]

🚨 IMPORTANT

This issue is likely user-facing in the main PostHog app, see surveyVersionRequirements.ts. If you delete or close this issue, be sure to update the version requirements list there.

Summary

The Android SDK does not support event property filters for survey event triggers. Currently, onEvent(event: String) only matches on event name, ignoring any property filter conditions.

Current State

• PostHogSurveysIntegration.kt line 827-846: onEvent(event: String) only receives the event name
• Event-to-survey mapping only checks if the event name matches, not property filters
• The survey model may parse propertyFilters but they are never evaluated in matching logic

Expected Behavior

When a survey is configured with event triggers that have property filters (e.g., "show survey when button_clicked event has button_name = 'signup'"), the SDK should:

1. Receive the event properties along with the event name
2. Evaluate the property filters using the same comparison operators as posthog-js
3. Only activate the survey if both event name AND property filters match

Reference Implementation

See posthog-js browser: packages/browser/src/utils/event-receiver.ts - the _doesEventMatchFilter method and matchPropertyFilters function in property-utils.ts
