Draft ADR-010 frontend hook contract; relabel Equipment to Machines

ADR-010 (PROPOSED): four data-only frontend hooks following the
get_reports precedent - get_settings_cards, get_asset_panels,
get_map_overlays, get_asset_presentation - batched as a future contract
0.7.0. Warranty proves asset panels first, measuringtools the rest;
accept only after both run on the hooks.

Display-label swap Equipment -> Machines across nav, list, form,
detail, search, map editor, and settings copy (incl the API-failure
fallback nav). Identifiers unchanged: plugin name, tables,
/api/equipment, asset type, and routes all stay.
