[FIX] product_sale_price_from_pricelist: Clean up old ir_property records

Fixed error: TypeError: float() argument must be a string or a real
number, not 'dict' when entering decimal values in product form.

Added post-migration to delete ir_property records left over from when
fields were company_dependent. These leftover records were causing dict
values to be passed to Float fields during onchange operations.

Migration checks if ir_property table exists to handle fresh installs
gracefully.

Version bump: 18.0.2.3.0 -> 18.0.2.4.0
