test(e2e): share Android WebView helpers via multi-platform WebView API

[cmd-ob]

Description

Android WebView tap/fill/read lived behind snaps-only helpers and TestSnaps had many isAndroidAppium() branches. This PR introduces a multi-platform WebView framework facade (tapById / fillById / readTextById) that routes Android Appium to AndroidWebViewNative and iOS Appium/Detox to the existing web-context + Gestures path. TestSnaps now uses that single API, snaps helpers keep only scroll labels + load wait, and tab cleanup moves behind Browser.navigateToURL({ closeAllTabsIfOpen }).

Manual testing steps

N/A — E2E framework refactor only; no product UI changes. Validate by running existing Appium snap smoke specs (Android + iOS) and confirming Detox snap smoke still exercises TestSnaps via the shared WebView path.

Screenshots/Recordings

N/A — test framework / page-object refactor with no user-facing UI changes.
