The header menu had Tasks but nothing for the schedules whose results
land in that conversation. It now has Schedules, right under Tasks,
opened in a modal that lists only what runs there: a bot's own chat holds
the routines that run nowhere, a workspace only that bot's routines in
it (`routineScopeSql`, tested against SQLite).
The list loads when the modal opens, through
`api/admin/bots/list-routines`, which checks the user chats in that
conversation first, so the page props stay small. `grabCronJobs` gained
an optional `workspace_id`: left out it still means everywhere.
The routines page's row, form and edit modal moved to
`src/components/general/`, and its subtitle to `src/utils/`, since both
the page and the modal use them.
