feat(jpush): add vendor-specific message classification support for push notifications

- Add OPPO category/notify_level support (2024.11.20 regulation: category required when notify_level present)
- Add Honor importance field (NORMAL=service/LOW=marketing) for notification classification
- Add vivo category field (IM/ACCOUNT) for message scenario identification
- Set Xiaomi channel/template defaults in code (system=153609, chat=153608, templates P10761/M10289)
- Add classification option to JPush push payloads (0=operation, 1=system)
- Update xiaomi template keywords mapping to match actual template placeholders
- Add keyword search support for GetFollowers and GetFollowing endpoints
- Bind new config fields to environment variables for OPPO/Honor/vivo
