fix(#7907): send_message_to_user cron 场景下 session 容错 (#7911)

* fix: send_message_to_user cron 场景下 session 容错 (#7907)

- LLM 在主动场景可能只传 session_id 而非完整三段式,
from_str 失败时用 current_session 补全前两段。

Co-authored-by: Copilot <copilot@github.com>

* fix: 限制 session 补全仅对裸 session_id 生效,避免误修带冒号的错误输入 (#7907)

* feat: add session information to cron job payload

Co-authored-by: Copilot <copilot@github.com>

* fix: improve clarity and consistency of safety mode prompts
