Add the affine display-transform registry (kg↔lb, cm↔in, °C↔°F with the
temperature offset carried as an absolute-only shift), a single client hook
that reads the preference, and a shared inbound unit-alias resolver. Wire the
manual entry form to label, prefill, and convert at the boundary so an imperial
reading persists in canonical SI, and route the record list value cells and
edit dialog through the same choke point. Close the one write path that could
persist a non-canonical unit: the MCP log_measurement tool now resolves a unit
hint to canonical or refuses it, reusing the resolver the CSV importer already
relied on.
