Adds a destructive-variant button at the top of the heartbeats page that
disables timer heartbeats for all agents at once. The button only appears
when at least one agent has heartbeats enabled, and shows a loading state
while processing.

Move useMemo and derived state above early returns so hooks are always
called in the same order. Simplify the description to plain English
and change toggle button labels to "Enable Timer Heartbeat" /
"Disable Timer Heartbeat" for clarity.

Group agents by company with a single card per company and dense
inline rows instead of one card per agent. Replaces the three stat
cards with a slim inline summary. Each row shows status badge, linked
agent name, role, interval, last heartbeat time, a config link icon,
and an enable/disable button.
