e2a09a648b [management] Save account row before users in setup realstore test
users.account_id is a foreign key into accounts on MySQL/Postgres, so
saving users for an account that has no row fails with a constraint
violation there while passing on sqlite.

a2be755b7d [management] Add Agent Network access roles and self-service endpoints
Delegating Agent Network today means handing out full account admin, and
regular users cannot see their own usage or how to connect a local tool.

Add two roles on top of the existing agent_network permission
submodules. agent_network_admin owns the whole area (providers,
policies, guardrails, budgets, usage, logs, settings) with read-only
users, groups, peers, and account info needed to build policies, and
nothing else in the account. usage_viewer is the regular User baseline
plus read on the aggregated usage and cost overview: no provider
configuration, no policies, no request-level logs, which can contain
captured prompts. billing_admin gets a proper permission-map entry with
the User baseline so role resolution stops failing with role-not-found;
its plan and invoice permissions stay enforced cloud-side.

Add the self-service endpoints behind the "My Agent Network" view,
available to every authenticated user because both answers are scoped
strictly to the caller. GET /api/agent-network/me/setup returns the
account endpoint plus the providers and models the caller's own groups
authorize, computed with the same rules the proxy enforces: policy
filtering as in policy selection, model allowlist union intersected
with declared models, orphan and disabled providers omitted. Not set up
and no access are deliberately indistinguishable, and the response
carries display metadata only. GET /api/agent-network/me/consumption
returns the caller's own user-dimension counters.

— the management-side control plane: providers, policies, guardrails, limits, routing,
and usage/access logs.
## Access roles
Agent Network permissions build on the account permission matrix
([`management/server/permissions/`](../management/server/permissions)). The
`agent_network` area is split into dotted submodules (`agent_network.providers`,
`.policies`, `.guardrails`, `.budgets`, `.usage`, `.logs`, `.settings`); a role may
grant a single submodule or the parent, which cascades to all of them.
Two roles delegate Agent Network access without account-admin rights:
- **`agent_network_admin`** — full control over the whole `agent_network` area plus
read-only users, groups, peers, and account info (needed to build policies).
Nothing else in the account.
- **`usage_viewer`** — the regular User baseline plus read on
`agent_network.usage` (the aggregated usage and cost overview). No provider
configuration, no policies, no request-level access logs.
Every authenticated user, regardless of role, can read the caller-scoped
self-service endpoints: `GET /api/agent-network/me/setup` (the endpoint, providers,
and models the caller's own policies allow — what a local AI tool needs and nothing
more) and `GET /api/agent-network/me/consumption` (the caller's own token and cost
counters). Role definitions live in
[`management/server/permissions/roles/`](../management/server/permissions/roles).
