Completes #1159 end-to-end with solid and suspended-floor before/after cascade pins on cert 001431, both closing at delta 0.000000. Adds floor_insulation_type_str to BuildingPartOverlay (the generic field-fold applicator picks it up with no change) and has recommend_floor_insulation set it to "Retro-fitted". Insulating an as-built floor re-lodges its insulation as retro-fitted; the calculator keys on this for a suspended timber floor's sealed/unsealed determination (cert_to_inputs.py: "retro" + no U-value supplied → sealed). Without it the suspended-floor cascade left a +1.40 SAP gap (the floor stayed "unsealed", wrong U-value); with it the cascade closes exactly. Solid floors are unaffected by the seal logic and stay at delta 0; both Elmhurst after-certs lodge "Retro-fitted", so setting it uniformly is faithful.
