Description

Adds the Compose DaxAppTPBanner to the ADS. It renders a DaxCard whose whole surface is a single tap target, with the message on the left and a state pictogram on the right:

• DaxAppTPBanner(text: String, …): plain message.
• DaxAppTPBanner(text: AnnotatedString, …): for the bolded lead-in the App Tracking Protection states use.

DaxAppTPBannerState selects the pictogram: Protected or Warning.

The two pictograms move from vpn-impl into the design system so the component can own them, and the existing AppTP screens now reference them from there.

No lint rule: there is no raw Material equivalent to guard against.

Steps to test this PR

ADS catalog

• Install an internal debug build
• Open Settings -> "Android Design System Preview" -> Messaging tab
• Scroll to the bottom, past Remote Messaging Framework, Info Panel and Snackbar
• Verify four banners render: Enabled, Trackers Blocked, Disabled, Revoked
• Tap a banner and verify a snackbar appears, and that the ripple is clipped to the rounded corners
• Confirm the above in both light and dark themes (Others tab -> Enable Dark Theme)
• Compare the Compose component against Figma (do not compare against XML as it's not based on Figma)

App Tracking Protection screens (the pictograms moved modules)

• Enable App Tracking Protection
• On the New Tab page, verify the AppTP card still shows its pictogram in the enabled, disabled and revoked states
• Open the Device Shield screen and verify the same
• Open the "Restore defaults" dialog in AppTP settings and verify its image still renders

Maestro

• Run maestro test .maestro/ads_preview_flows/1-_design-system-components.yaml with the app installed

Note

Low Risk
Mostly new Compose UI and drawable relocation with reference updates; no VPN or auth logic changes.

Overview
Introduces DaxAppTPBanner in the Android Design System: a full-width, tappable DaxCard with message text (plain or AnnotatedString) and a Protected / Warning pictogram via DaxAppTPBannerState.

AppTP banner assets (ic_apptp_banner_default, ic_apptp_banner_warning) are centralized in the design system; vpn-impl New Tab, Device Shield, and restore-defaults UI now reference those shared drawables instead of module-local icons.

The ADS Messaging catalog gains an App Tracking Protection Banner section (four sample states) plus Maestro scroll/assert steps for the Enabled and Revoked showcase headers.
