refactor(names): agent resolution + one error type

Adopt the simplexmq names rework (PR #7045): name resolution is now
owned by the agent (resolveSimplexName picks a names-role server), so
the chat-side iteration is removed - delete ResolveError,
iterateResolvers, resolveOnUserServers, enabledSMPServersForUser and
resolveErrorToChatError.

One error type: resolver/agent failures flow through ChatErrorAgent;
remove the CEvtSimplexName* events, SimplexNameVerifyFailReason,
SimplexNameConflictEntity and CESimplexNameResolverUnavailable.
APIVerifySimplexName returns CRSimplexNameVerified (verified::Bool),
mirroring CRConnectionVerified. connectPlan handles the name target
directly; updateProfile WithConflict aliases collapsed into the plain
functions.

Add the per-operator "names" SMP server role (migration
20260612_smp_role_names, official operator on by default) feeding
ServerRoles.names -> UserServers.nameSrvs.

Bump simplexmq pin to ce69adfd and regenerate sha256map.nix.
