Accept + implement ADR-010 frontend plugin hooks (contract 0.7.0)

Four data-only hooks on BasePlugin (get_settings_cards,
get_asset_panels, get_map_overlays, get_asset_presentation) with a
GET-only /api/pluginui consumer surface copying the dashboard-widgets
semantics. Pilots: warranty declares its asset panel; measuringtools
supplies its settings card, presentation, and calibration overlay -
the last hardcoded settings-nav entry is now hook-sourced. Generic
renderers for panels/overlays/presentation deferred per the ADR's
incremental adoption plan (documented in CONTRACT-STABILITY.md).
