[Android] "What’s New" promo message: Implement pixels

[anikiki]

Task/Issue URL: https://app.asana.com/1/137249556945/project/1200581511062568/task/1211783737656685?focus=true

Description

Added pixel tracking for CardsList remote messages. This PR introduces a new CardsListRemoteMessagePixelHelper class that handles firing pixels for card-specific events (shown, clicked, dismissed) with appropriate parameters. The implementation tracks when cards are shown to users, when users interact with cards, and how messages are dismissed.

Steps to test this PR

CardsList Remote Message Tracking

• Verify that when a CardsList message is shown, the m_remote_message_card_shown pixel fires for each card
• Verify that when a card item is clicked, the m_remote_message_card_clicked pixel fires with the correct card ID
• Verify that when a message is dismissed via close button or via the back navigation, the m_remote_message_dismissed pixel fires with the appropriate dismiss type parameter
• Verify the other existing RMF pixels are fired (message shown, primary action clicked)

NO UI changes

Note

Implements CardsList RMF pixels (shown/clicked) and dismissal tracking (close/back) with view model wiring and back navigation handling, plus pixel definitions and tests.

• Remote Messaging (CardsList):
  • Pixels: Fire m_remote_message_card_shown for each card on message render and m_remote_message_card_clicked on item click via CardsListRemoteMessagePixelHelper.
  • Dismiss Tracking: Fire m_remote_message_dismissed with dismiss_type (close_button/back_button_or_gesture) and dismiss via repository.
  • ViewModel Updates: Track last message; call RemoteMessageModel.onMessageShown and onPrimaryActionClicked; wire onMessageShown() from view render.
  • Back Navigation: ModalSurfaceActivity intercepts back; ModalSurfaceViewModel.onBackPressed fires dismiss pixel (CardsList) then closes.
• Pixels Definition: Add RMF pixel specs in PixelDefinitions/pixels/remote_messaging_framework.json5 (including m_remote_message_card_shown, m_remote_message_card_clicked, and dismiss_type enum).
• Tests: Add unit tests for helper, view models, and back-press dismissal pixels.

Bug: Pixel parameter name mismatch with JSON5 definition

The constant PARAM_NAME_DISMISS_TYPE is defined as "dismissType" (camelCase), but the pixel definition in remote_messaging_framework.json5 specifies the parameter key as "dismiss_type" (snake_case). This mismatch will cause the dismiss type parameter to not be properly recognized by the analytics system, resulting in anonymous measurement data being lost or incorrectly categorized.

Bug: Missing duplicate prevention for "shown" pixels

The onMessageShown() call in render() lacks the duplicate prevention check present in the existing RemoteMessageView. The ViewModel computes newMessage (line 70) but doesn't include it in ViewState or use it to guard pixel firing. In contrast, the existing RemoteMessageView uses shouldRender = newMessage || binding.root.visibility == View.GONE before calling onMessageShown(). Without this check, the card "shown" pixels will fire every time render() is called with the same message, such as after configuration changes, leading to duplicate anonymous measurement data.
