The JPush API returns sendno as a string value in the JSON response, but the
struct field was incorrectly typed as int64. This fix updates both the struct
field type and the corresponding zap logger call to use string type, ensuring
proper JSON parsing and logging.
Add zap logger calls to Track, PushByRegistrationIDs, PushByAliases, PushAll,
and GetDeviceInfo methods for improved observability. Logs include request
debug info, response parsing status, success confirmations, and error
tracking with relevant context like message IDs, counts, and registration IDs.
Add JPush (极光推送) integration to enable push notifications for offline users. This includes:
- New jpush client package with API for batch push notifications
- Configuration for jpush (enabled, app_key, master_secret, production mode)
- Updated push service to send messages via JPush when users are offline
- Added PushChatMessage method with do-not-disturb checking
- Integrated push service with chat service to notify offline users of new messages
- Updated deployment workflow with JPush and related environment variables
