refactor(api-server): move agents-standup SQL into db domain methods

Replace the six inline queryAll calls in routes-agents-standup.ts with
typed domain methods: db.agents gains listDirectReportsForStandup and
listReportStatusesForStandup (LEFT JOIN aggregation), db.tasks gains
listAssigneeTasksForStandup and listTasksForAssignees (safe on empty
assignee list), db.approvals gains listAgentPendingApprovals and
listAgentResolvedApprovals. Shared listRecentTaskComments is reused.
