fix: use company currency instead of global default in report (backport #56561)

Reports like Sales Order Trends and Purchase Order Trends showed the global
default currency symbol instead of the transacting company's currency.

Threads the company currency through conditions["company_currency"] in
trends.get_columns and uses it for both the chart's currency and the Total
row. The chart now skips the grand-total row by its label instead of by a
falsy first periodic cell, so the already-summed Total row is not added into
the datapoints a second time.

Backport of #56561 (frappe/erpnext). Two parts of the original PR are not
included: the Landed Cost Report does not exist on this branch, and the
trends report test files do not exist either.
