fix(dashboard): restore accurate executing/total column headers

Show live agents over card count (e.g. 3/4) using the shared Running
predicate so unpaused WIP counts without sessionFile, and document the
badge semantics for operators.

 summary: Unify max concurrency across planning/execution/review and simplify board capacity indicators.
 category: feature
-dev: maxConcurrent caps all top-level working agents per project; maxTriageConcurrent removed from UI (Settings, Command Center, Engine Control) and admission; free slots admit oldest createdAt via per-project atomic admission coordinator across lanes; footer Waiting/Running/Blocked; column headers remain card totals; Running counts unpaused WIP membership (sessionFile is not a DB/board field — do not require it); nested runNested helpers remain parent-internal soft-breach by design.

 <!-- FNXC:CommandCenterActivity 2026-06-30-00:00: Activity active-agent counts include both durable-agent usage events and ephemeral task-worker execution runs from agentRuns, because task execution can be visible without a matching usage_events row. -->
 <!-- FNXC:CommandCenterActivity 2026-07-01-00:00: Graph-owned workflow step sessions publish active-to-terminal agentRuns lifecycle rows with task lineage and step metadata, so daily activity and Activity throughput charts include new workflow execution without dashboard-side recounting. -->
-- **Overview controls dashboard** includes AI engine stop/start backed by `globalPause`, the shared Global Max Concurrent slider, and current-project **Max concurrency** plus **Max worktrees** controls. Max concurrency caps top-level working agents across planning, execution, and review/merge; free capacity is admitted oldest-first within the project. The footer reports **Waiting**, **Running (N/max)**, and **Blocked**; column headers report the card count in each lane.

+- **Overview controls dashboard** includes AI engine stop/start backed by `globalPause`, the shared Global Max Concurrent slider, and current-project **Max concurrency** plus **Max worktrees** controls. Max concurrency caps top-level working agents across planning, execution, and review/merge; free capacity is admitted oldest-first within the project.

 <!-- FNXC:TeamArea 2026-07-18-12:30: FN-8351 moves organization export and import to the Team tab so team-level portability controls are not presented as Overview dashboard controls. -->
 - **Team tab — Org export / import** lets an operator download a portable organization JSON bundle or paste one for a dry-run preview before confirming the apply step. Exports are secret-scrubbed by default: credentials and tokens are never included, while safe secret references can remain for setup in the destination project.
 - **Configuration versions** lives in **Settings → Project → Configuration Versions**. It lists recorded project-setting revisions newest first; select **Roll back** on any revision and confirm once to restore it. The restore is recorded as a new forward revision, so it can itself be undone without manually reconstructing settings.
