feat(RevenueCatUI): Tab selected-state (PWENG-65)

[AlvaroBrey]

Wires tab selection into the store: TabsComponent.stateUpdates fires on selection, publishing the selected tab id as a $value payload. Hidden tabs still publish on first composition so sibling components aren't left on stale state. The 4 reader component states (Text, Image, Stack, Icon) pass stateReader = stateStoreProvider()::currentValueOrDefault into ConditionContext.

End-to-end instrumentation tests for the read path (state condition drives a text swap) and write path (tab click publishes to store). Paywall-tester example (bottom text):

Note

Medium Risk
Touches paywall override resolution and shared component state across Text/Image/Stack/Icon; behavior changes for state-driven tabs but is scoped to RevenueCatUI with new tests.

Overview
Connects tab selection to the paywall state store so other components can react via state_condition overrides.

When a Tabs component is visible, TabsComponentView runs stateUpdates on first show and whenever the selection changes, writing the selected tab id (payload reference) into PaywallStateStore. Hidden tabs do not publish (store stays on declared defaults).

Text, Image, Stack, and Icon component states now pass stateReader = stateStore::currentValueOrDefault into ConditionContext, so overrides keyed on store values recompose when tab state changes. TabsComponentStyle carries stateUpdates and each tab style includes an id from the model.

Adds instrumentation tests for the read path (state override swaps copy) and write path (tab click updates store), plus a paywall-tester sample with selectedTab declarations and tab-dependent offer text.
