// attachWebSession hands a signed-in console user their session token.
//
// Added to the login response rather than served from a second endpoint, so the
// console receives it on the call it already makes and nothing changes about
// when or how it signs in.
//
// The claims come from the user's own record, which is the whole point: until
// now the console asserted its tenant on every request and was believed, and
// sealing it under a signature here is what makes `middleware.WebAuth` able to
// refuse a request naming somebody else's.
//
// `Issuperadmin` is copied across as the ONLY source of cross-tenant access.
// Not the role — `app_roles` calls roleid 1 "Super admin" and tenant onboarding
// wrote 1 for every shop owner, so trusting the role would promote every
// merchant on the platform.
//
// A failure to mint is logged and swallowed, deliberately, while
// WEB_AUTH_REQUIRED is off: a deployment that has not set a signing key yet must
// still be able to sign in, or shipping this takes the console down everywhere
// the secret is missing. Once enforcement is on, no token means no session —
// which is then the correct and loud failure.
//
// The parameter is the underlying map type rather than `fiber.Map`, because the
// two login paths do not agree on which fiber that is: `AppLogin` returns the
// v1 package's `Map` and `TenantWebLogin` the v2 one. Both are
// `map[string]any`, so taking that accepts either without dragging the
// old import into this file.
