Two registrations of the same route lived in the codebase: one inline
in routes-agents.ts that filtered three full company-wide SELECTs in
memory, and the dedicated routes-agents-standup.ts that uses targeted
standup-shaped DB queries. The router keeps the first match so the
inline copy was serving every request and the focused module was dead
code — any future fix to standup would have silently missed
production.
Remove the inline standup handler and its three companion helpers
(`listAgentsForStandup`, `listTasksForStandup`, `listApprovalsForStandup`)
plus the unused `AgentStandupRow` type. The dedicated standup module is
now the single source of truth.
