[FIX] pos_restaurant: exclude archived floors in get_tables_order_count

Before this commit, archiving a restaurant floor caused an error when
opening a PoS restaurant session. This issue originated from the
`get_tables_order_count` function, which executed a search based on
`restaurant.table`. Since archiving a floor does not automatically
archive its tables, the function returned information for archived
floors, leading to errors.

With this commit, we introduce an additional search to first identify
active floors in a PoS config. This refined search is then used to
filter tables, ensuring that only tables from active floors are
considered.
