Note

Medium Risk
Changes subscription feature/entitlement fetching logic at app startup to be controlled by a new remote flag, which could affect which base plans are queried and cached. Impact is limited in scope but touches subscription availability behavior.

Overview
Decouples pro-tier entitlements refresh from purchase availability by introducing a new privacyPro.fetchProTierEntitlements remote flag (default enabled).

SubscriptionFeaturesFetcher now uses this new flag (instead of allowProTierPurchase) to decide whether to include both Basic and Advanced subscription products when selecting base plans to fetch and cache subscription features/entitlements.
