fix(sync): prevent kit/bax price sync from overwriting individual CRM prices

Three code paths could overwrite CRM list prices with wrong values when
web unit (50 buc) differs from ROA unit (100 buc):

- price_sync_service: kit path now skips components that have their own
  ARTICOLE_TERTI mapping (individual path handles them with correct ÷0.5)
- validation_service: sync_prices_from_order now skips bax SKUs
  (cantitate_roa > 1) in addition to multi-component kits
- pack_import_comenzi: skip negative kit discount (markup), ROUND prices
  to nzecimale_pretv decimals

Also adds:
- SQL script for 6 ARTICOLE_TERTI mappings (cantitate_roa=0.5) for cup
  articles where web=50buc, ROA=100buc/set
- Oracle schema reference documentation
