feat: dashboard reads the sprint, the risks, aging and bottlenecks

A new projectInsights reading (GraphQL Project.insights, REST
/projects/{project}/insights, MCP get_project_insights), computed by pure
functions over the read model and the timeline:
- the sprint under way: days left, points done, pace against what is
  needed and whether it gets there;
- tickets at risk: overdue, due within a week, blocked by an open ticket
  and stuck (7 days or more in an in-progress or QA status);
- aging of the work under way against the p85 cycle time;
- average days in each in-progress and QA status, with WIP limits.
The dashboard shows them in four new panels, reloaded on every change.
