refactor(config): rename wakeup_system to sleep_system for clarity

This commit refactors the entire "wakeup system" to be named "sleep system". This change provides a more intuitive and accurate name for the functionality, which manages the AI's sleep cycles, sleep pressure, and related behaviors like insomnia and flexible sleep schedules.

The renaming has been applied consistently across all relevant files, including:
- Configuration models (`WakeUpSystemConfig` -> `SleepSystemConfig`)
- Configuration files (`bot_config_template.toml`)
- Core application logic that references these configurations.

Additionally, flexible sleep and pre-sleep notification settings have been moved from the `ScheduleConfig` to the new `SleepSystemConfig` to centralize all sleep-related parameters.
