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
Changes paywall override resolution and tab-driven state publishing across core component states; behavior is covered by new tests but affects dynamic paywall UI broadly.

Overview
Tab selection now drives shared paywall state so other components can react via state_condition overrides.

When a visible TabsComponent has stateUpdates, TabsComponentView seeds and updates the store with the selected tab id (payload reference) on first composition and on every selection change; hidden tabs do not publish (iOS parity). TabsComponentStyle carries stateUpdates, and each tab style entry now includes an id.

Text, Image, Stack, and Icon component states pass stateReader = stateStore::currentValueOrDefault into ConditionContext, so overrides keyed on store values re-resolve when tabs (or anything else) updates state.

The paywall-tester TabsWithButtons sample adds selectedTab declarations, tab stateUpdates, and offer copy that swaps when selectedTab equals tab-1. Compose instrumentation tests cover store-driven text overrides, tab-click publishing, and hidden-tabs behavior.
