DottaandClaude Opus 5.5 b07399c241 fix(authz): link the project's access settings when an agent cannot share a project (#20176)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Some actions are board-only. When an agent calls one, the 403 denial
tells it that the denial is final and, when known, links the board page
that holds the control
> - Project sharing (`/api/projects/:id/access-members`) had no known
page, so the denial told agents to link a page only if they already knew
its route
> - An agent asked to "Let Riley see the acquisition project" got this
denial. It told the person to look for "access/sharing settings" and
gave no link, so the person had to search for the control
> - This pull request maps project access-member routes to the project's
Configuration page, where the Manage access control is
> - The benefit is that agents give people a direct link to the control
that shares a private project

## Linked Issues or Issue Description

Bug report (no public issue exists).

**What happened**
An agent tried to add a person to a private project. `POST
/api/projects/:id/access-members` returned 403 "Board access required"
without a page link. The agent told the person to find the project's
access or sharing settings in the web app and gave no link.

**Expected behavior**
The denial links the project's Configuration page
(`/<prefix>/projects/<id>/configuration`), where Manage access is. The
agent gives that link to the person.

**Steps to reproduce**
1. Create a private project and give an agent access to it.
2. In chat, ask the agent to let another company member see the project.
3. The agent's access-member request is denied, and its reply has no
link to the sharing control.

Refs #20151

## What Changed

- `server/src/routes/authz.ts`: board-only denials for
`/projects/:id/access-members` (and its member subpaths) link "the
project's access settings" at `/<prefix>/projects/<id>/configuration`.
The link uses the resolved route project ID, so short references such as
`/api/projects/acquisition/access-members` also get the link. Without a
resolved UUID, the denial falls back to the generic instruction.
- `server/src/__tests__/board-access-denial.test.ts`: cases for add and
remove access-member denials, plus a short-reference case that goes
through a route param resolver.

## Verification

- `cd server && npx vitest run
src/__tests__/board-access-denial.test.ts` passes (17 tests). The
short-reference test fails on the previous matcher. The server `tsc
--noEmit` passes.
- The chat eval `projects.share-project` found this gap: in one run the
agent linked the project, and in the next run it gave no link.

## Risks

- Low risk. This changes only the remediation text in an agent's 403
response. It does not change authorization.

## Model Used

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