docs: align Community and Admiral assurance positioning (#1632)

Reframe docs, OpenAPI registries copy, and License trial/expiry helpers
so Community is the full AGPLv3 product and Admiral leads with current
assurance (Hardened Build, Recovery Vault, support, governance).
Mesh, Secrets, and Host Console stay limited-availability without
Admiral sales framing.
