Description

Updates logic to decide if we should add origin in our attributed metrics.
This now relies on remote config.
if enabled, we validate if origin includes specific substrings, otherwise we don't include.

Steps to test this PR

Update the PrivacyFeatureName PRIVACY_REMOTE_CONFIG_URL with https://duckduckgo.github.io/privacy-configuration/pr-4110/v4/android-config.json

Use logcat filter package:mine message~:"attributed_metric"

Feature 1

• Fresh install (removing local folder)
• Launch and wait for Skip onboarding to appear.
• skip onboarding
• Go to internal Attribute Metrics
• Add search events, add ad clicks, add duck ai events
• update app retention atb and search atb with random values
• Update origin with funnel_paid_test
• put install date in the past, 1mo works
• restart (fire button)
• you should see some pixels from attributed metrics, they should contain origin

Feature 2

• Go to internal Attribute Metrics
• update app retention atb and search atb with NEW random values
• Update origin with funnel_test
• restart (fire button)
• you should see some pixels from attributed metrics, even if ignored, they should contain install_date now

Pull Request Overview

This PR introduces remote config-based control for including origin parameters in attributed metrics. Instead of always sending the origin when available, the system now validates the origin value against configured substrings before including it in metrics.

Key Changes

• Introduces OriginParamManager class to encapsulate origin validation logic based on remote config
• Adds new sendOriginParam feature toggle with configurable substring matching
• Updates metric emission logic to conditionally include origin or fall back to install_date
