Khalim Conn-Kowlessar 0ffda529ec slice 15a: add wall/floor/roof + demand scalar features for retrofit simulation
15 new features wired through schema -> domain -> mapper -> transform:

Main Dwelling fabric (11):
  - wall_insulation_type, wall_insulation_thickness_mm, wall_dry_lined,
    wall_thickness_mm, party_wall_construction
  - roof_insulation_location, roof_insulation_thickness_mm
  - floor_construction, floor_insulation, floor_insulation_thickness_mm,
    floor_heat_loss

Dwelling-level scalars (4):
  - multiple_glazed_proportion, number_baths, number_baths_wwhrs,
    extract_fans_count

Thickness strings like '50mm'/'NI'/'ND' parsed via _parse_thickness_mm; NI
(no insulation) lands as 0mm so the model sees the physical zero rather than
a missing value. Categorical sentinels ('NA'/'NI'/'ND') become None.

Also fixed long-standing typo `multiple_glazed_propertion` -> `_proportion`
in domain dataclass + its lone DB-model usage.

Shared packages

Workspace packages consumed by services/*. Each package is its own Python distribution with its own pyproject.toml; services import via the workspace dependency mechanism ({ workspace = true }).

Package Purpose
domain/ Shared domain types — Property, BaselinePerformance, Plan, Scenario, EpcPropertyData, etc. No persistence, no IO, no business logic.
repos/ Persistence layer — one repo per aggregate. Owns the SQL. Depends on domain.
fetchers/ External API clients (gov EPC, Ofgem, Google Solar, etc.). Depend on domain for response shapes.
utils/ Cross-cutting infra — logging, S3, CloudWatch URL builders, SQS task helpers.

Adding a new shared package

Only when a real second consumer materialises. Don't pre-shatter (repos-epc, repos-property, ...) — split when a deployment needs to drop a dep, not before.

See ../ara_backend_design.md §11 for the broader monorepo layout and ../CONTEXT.md for the domain glossary that names the types living in domain/.
