[FIX] account, web: display total and subtotals correctly rtl lang

Issue :
After the last fix https://github.com/odoo/odoo/pull/124663


there is still an issue of currency placements and alignement
of numbers in rtl language at the total and subtotals.

Steps to reproduce the isse :
1-create an invoice and confirm it.
2-install accounting
3-go to accounting/customer invoices and choose the created invoice

Origin of the problem :
The fields displayed didn't have the appropriate classes and the
style for number and monetary values for rtl language is missing from
the css folder.

Fix:
I applied the class on the `td` tag and `span` tag.
