feat(web,mobile): one scheduled-task list and editor for agents and threads (#226)

* feat(web,mobile): one scheduled-task list and editor for agents and threads

Settings and Agents → Scheduled now share one list with an All / Agents /
Threads / New thread / Archived filter and one editor that can pick an
agent and edit cron schedules. Mobile gets the same filter, agent
destination and cron editing. The thread Automations section can start a
task bound to that thread.

* fix(web): hide the thread Automations section until the thread has a task

* fix(server): leaving an agent no longer keeps the agent's old thread

Moving an agent task to Continue or Fresh session with no thread chosen sent
profileId: null and threadId: null, and the save coalesced the null back to
the agent's thread. Later runs then went into that conversation with its
model and modes. Leaving an agent with an explicit null thread now clears the
binding; an omitted threadId still keeps it.
