feat(api/v2): add nested task comment CRUD

Add TaskComment CRUD on /api/v2 under /tasks/{task}/comments, mirroring
the project_views nested-resource shape. The resource is feature-gated by
config.ServiceEnableTaskComments, checked inside the registrar so it runs
after config has loaded. Self-registers via init()+AddRouteRegistrar; no
routes.go change. ReadAll exposes the order_by (asc/desc) query param.

Adds doc:/readOnly: tags to the shared TaskComment model fields and a
TestHumaTaskComment webtest covering list/read/create/update/delete plus
negatives (non-author forbidden, comment under the wrong task -> 404).
