[management] Resolve agent network permissions per submodule

Agent Network gates providers, policies, guardrails, budgets, usage,
access logs, and settings behind the single agent_network module, so
access is all-or-nothing and a delegated role cannot be scoped to a
subset of the area.

Introduce dotted submodules (agent_network.providers, .policies,
.guardrails, .budgets, .usage, .logs, .settings) and resolve grants
with a cascade: exact module, then its parent, then the role's
AutoAllowNew default. The agent network manager now checks the
submodule matching each operation.

No role definitions change: no built-in role carries an explicit
agent_network entry, so every role resolves the submodules exactly as
it resolved the parent module before, pinned by tests.
