Interface Loopback Module Support for config_actions + resource level deploy

#366

Status (2026-07-24): In flight via PR #366 (draft) — "nd_interface_loopback: align deploy control to config_actions.deploy". On track for September pending team PR review completion.

nd_interface_loopback predates the config_actions convention; PR #366 brings it in line with the other nd_interface_* modules: config_actions.deploy (default true), with deploy resource-scoped — a single bulk interfaceActions/deploy call at the end of the module run covering only the interfaces listed in the task.

Scope note vs. the full #368 contract: only the deploy suboption is exposed. save is not applicable to interface modules, and type (resource/switch/global) plus the per-resource deploy key are deferred pending resolution of #368. The implemented behavior is equivalent to type=resource — deploy is scoped to exactly the interfaces in the task.
