Jun-te Kim 5b4a1b4966 Classify PCDB-index gas boilers with no SAP code for heating recs
Gov-API certs that lodge a gas boiler as main_heating_category=2 + a PCDB
main_heating_index_number but omit sap_main_heating_code were carried with
a null code, so the heating generators (which gated on sap_main_heating_code
alone) never evaluated them for a boiler upgrade or a system tune-up — they
silently got nothing (£0 works, plateau at D). The SAP calculator already
handles this shape (cert_to_inputs._is_wet_boiler_main), so the calculator
modelled these as wet boilers while the recommenders ignored them.

Mirror the calculator's classification in the generator:
- _is_wet_boiler / _is_electric_boiler fall back, when no SAP code is
  lodged, to a PCDB Table 105 boiler index or main_heating_category in
  {1,2} (heat pumps excluded); electric boilers stay excluded by the code
  range when lodged, else by an electricity main fuel.
- _already_condensing reads the boiler's declared PCDB winter efficiency
  when there is no Table 4b code, so a modern condensing boiler lodged this
  way still isn't offered a pointless like-for-like swap (gets a tune-up).

Verified read-only on portfolio 814 / scenario 1271: pids 742304, 742306,
742322, 742325, 742336 now get a gas_boiler_upgrade (two cross D->C on the
boiler alone) where they had £0 works; predicted properties whose heating
donor is a PCDB-shape boiler (e.g. 742095/742102/742105) also recover a
tune-up. Fixes the A#2 slice of #1388 (and unblocks 742302/742367).
