fix(costs): mark unpriced usage in the agent, model and project cost reports (#20889)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Cost reports show what agents and projects spent
> - A run can have usage with no known price; Paperclip saves it with
costStatus "unpriced" and costCents 0
> - The summary and the provider, biller and user reports count those
events, but the agent, agent-model and project reports did not
> - An agent that read the by-agent-model report saw a native run at
costCents 0 and told the person it cost $0.00
> - This pull request adds unpricedEventCount to those three reports and
tells agents what it means
> - The benefit is that missing charges are reported as unpriced, not as
free

## Linked Issues or Issue Description

**What happened**
In the chat eval budgets-costs.spend-breakdown, the person asked "How
much did Launch cost this week, broken down by agent?". The week
included a real native run whose usage had no known price (data-quality
reason missing_price). The agent read /costs/by-agent-model and
/costs/by-project. Both returned costCents 0 for that usage and no
unpriced count. The reply showed "1 native run ($0.00)" and gave the
total as complete.

**Expected behavior**
The reports say which rows include unpriced usage. The agent says that
usage is unpriced, marks the total incomplete, and links the record.

**Steps to reproduce**
1. Record one priced and one unpriced metered cost event for an agent in
a project.
2. Call GET /api/companies/{companyId}/costs/by-agent, /by-agent-model
and /by-project.
3. See costCents counts only the priced event, and no field shows the
unpriced event.

## What Changed

- `costService.byAgent`, `byAgentModel` and `byProject` return
`unpricedEventCount` (same filter as the summary: unpriced and not
subscription_included).
- Shared types `CostByAgent`, `CostByAgentModel` and `CostByProject` add
`unpricedEventCount`.
- The OpenAPI catalog entries for the cost reports that count unpriced
usage now say that costCents counts priced usage only, that unpriced
usage must be reported as unpriced (never $0.00), and that
/costs/data-quality lists those runs.
- Tests: embedded-Postgres service test (red on master, green here) and
an OpenAPI description test. A UI test fixture adds the new field.

## Verification

- `npx vitest run src/__tests__/costs-service.test.ts` (19 passed). The
new test fails with the master service.
- `npx vitest run src/__tests__/openapi-routes.test.ts
src/services/native-runtime/runner-api.test.ts` (2146 passed).
- `tsc --noEmit` for packages/shared and server.

## Risks

- Low risk. One added aggregate column per report and an added response
field. The UI does not read it yet.

## Model Used

- Anthropic Claude Opus 5.5 (`claude-opus-5-5`), tool use and code
execution in Claude Code.
