feat: Sentinel mode support

- NewConnectionDialog: sentinel toggle + host/port/masterName/nodePassword form
- connection.ts: use ioredis sentinels config when sentinelEnabled
- Add sentinelEnabled/sentinelHost/sentinelPort/sentinelNodePassword to all types
- i18n keys for all sentinel fields (zh-CN + en)
