refactor(dashboard): delete redundant company-status line + arbitrary animation cap

Two subtractions surfaced by the fresh Jony+Jobs pass on the Dashboard:

- The "Company status line" at the top of the dashboard showed three
  counters: `{activeAgents} agents active · {activeTasks} tasks in
  progress · {completed} completed`. The 4-card MetricsGrid directly
  below it already rendered the same agent count and active-tasks
  count as its primary tiles. Seeing the same number in vertical
  succession is the cheapest way to tell users "we weren't sure
  what to show." Deleted the whole status-line block + the companyName
  prop + the now-unused caller wiring in OperationsSections.

- The Active Work list rendered a `animate-ping` halo on the first
  two running runs (`i < 2`) and skipped it for the rest. Arbitrary —
  either the ping is a meaningful "I'm active" signal for every
  running run, or it is decoration. Dropped the ping entirely; the
  solid green dot on the robot icon is already enough to say
  "running," and losing the double-layered animation lets the
  dashboard feel calm instead of twitchy.

Dead i18n keys removed alongside (zh + en):
  dash.agentActive / dash.agentsActive / dash.taskInProgress /
  dash.tasksInProgress / dash.completedCount.

Typecheck clean.
