7 Leyton Avenue (UPRN 100031252876) came back from OS Places as RH03
("HMO Not Further Divided") and rendered as "Non-residential", so it
couldn't be added from the postcode-search "add properties" journey.
classifyOsCode decided "residential?" purely on an RD prefix, dropping the
whole RH (HMO) family — even though RD07 (the RD-family HMO code) was
already mapped to House. Extend the residential check to RH and map
RH01/RH02/RH03 to House (built form unknowable), consistent with RD07.
Updates ADR-0007's enumerated mapping table to stay truthful.

The docs/adr/** ignore rule silently ate ADRs 0004-0006 that CONTEXT.md
still references. Remove it so decisions actually land in the repo.
