Voegt een verplicht code-veld toe aan Sprint, sequentieel per product
(consistent met PBI-N, ST-NNN, T-N).
- **Schema** — `Sprint.code String @db.VarChar(30)` + `@@unique([product_id, code])`
- **Migratie** — voegt kolom toe als nullable, backfillt bestaande sprints
via `ROW_NUMBER() OVER (PARTITION BY product_id ORDER BY created_at)`
als `SP-N`, en zet daarna NOT NULL + UNIQUE.
- **Generator** — `generateNextSprintCode(productId)` in lib/code-server.ts
volgt het patroon van story/pbi/task; createSprintAction gebruikt
`createWithCodeRetry` voor race-bescherming.
- **Seed** — sprint-counter per product (`SP-1`, `SP-2`, ...).
Zichtbaar in:
- Sprint-header (`Product › Sprint actief · SP-3`)
- JobCard + JobDetailPane voor SPRINT_IMPLEMENTATION jobs
- Insights: VelocityChart x-axis (compacter dan goal-truncated),
AlignmentTrend tooltip, SprintInfoStrip
- actions/jobs-page.ts: `sprintCode` is weer een echte code i.p.v. null

The /insights page was rendering only Sprint Health (2 charts).
PRs #47/#48/#49 delivered helpers + tests for Velocity, Backlog health
and Agent throughput, but Velocity and Backlog never produced their
UI components, and none of the four new sections were wired into
page.tsx. Result: user sees 2 charts where 5 sections were promised.
This PR fills the gaps:
- New `app/(app)/insights/components/velocity-chart.tsx` — Recharts
grouped BarChart with optional ReferenceLine for the average. Empty
state when <2 completed sprints.
- New `app/(app)/insights/components/backlog-health.tsx` — counters
(stories sans AC / tasks sans plan / stuck>7d) + stuck-tasks table
with severity-coded days-stuck cell.
- `app/(app)/insights/page.tsx` rewritten as 5 sections:
Sprint Health, Plan-quality (donut + alignment-trend), Agent
throughput, Velocity, Backlog health. Helpers run in one
Promise.all so the page renders in a single tick.
Tests: 314/314 green, tsc clean, lint 0 errors.
