feat(phase4): list/set/zset editors, CLI, slow log, DB selector

- ListEditor: pagination, push, edit, remove elements
- SetEditor: filter, add, remove members
- ZsetEditor: filter, add with score, remove members
- CliView: interactive terminal with command history
- SlowLogView: slow log table with time/duration/command
- DbSelector: dropdown to switch Redis databases (0-15)
- StatusBar integrated with DB selector
- MainArea: added CLI and Slow Log tabs
- KeyDetail: dispatch to List/Set/Zset editors
- RedisService: list/set/zset/slowlog/memory operations
- Preload: all new IPC channels typed
