feat: add WeChat Pay, Redis logging, storage tiers and personal albums

Replace virtual payments with WeChat Pay API v3 and verify callbacks and order polling. Cache WeChat access tokens in Redis and write structured Zap logs. Support configurable capacity plans across the API, admin and mini program, with purchase snapshots and quota enforcement. Allow personal albums before binding and share them with the current partner. Update deployment configuration and domain routing.
