Promotes the `minimum-implicit-member` experiment to GA and removes it.
## What changes
- The `minimum-implicit-member` experiment constant, its
`RoleOptions.MinimumImplicitMember` toggle, and the global
`rbac.MinimumImplicitMember()` accessor are deleted. The minimal-member
behavior is now the only behavior: `organization-member` and
`organization-service-account` carry only the floor (read-self records,
notifications, and similar) and grant **no workspace permissions**.
Workspace access lives exclusively on the
`organization-workspace-access` role.
- The experiment gate on customizing `default_org_member_roles` (`PATCH
/organizations/{org}`) is removed; the built-in-roles-only validation
remains.
- The dashboard's Default Roles section and the implied-roles display on
the members page are no longer experiment-gated.
- Admin docs: new "Default member roles" section in
`docs/admin/users/organizations.md`, cross-linked from
`groups-roles.md`.
## Why this is safe for existing deployments
Migration `000516` (shipped earlier) backfilled
`default_org_member_roles` with `['organization-workspace-access']` on
every organization. Members therefore keep exactly the effective
permissions they had with the experiment off; the workspace elevation
flows through the default role instead of being baked into
`organization-member`.
**Rollback caveat:** rolling back past this release restores the bundled
elevation, silently re-granting workspace access to members of
organizations that cleared their default roles.
## Review
Deep-review R1 findings are addressed in `chore: address deep-review
findings` (copy fixes, read-only Default Roles for viewers, removable
overlapping explicit grants, RBAC prose restoration, test
de-tautologizing, docs). Point-by-point disposition is in the PR
comments.

Closing websockets can race whether they return an error or not if the remote side closes too. Dropping some test assertions about this since it is not critical to what we are testing.
