[FIX] Corrected currency assignment for multi-company instances with …

…varying currencies.

Previously, Odoo defaulted to the currency of the first company when updating existing records.
This issue has been addressed by utilizing a computed field.

The `currency_id` field was being cut off at a 120% zoom level.
By assigning the field to its own group, this display issue has been resolved without impacting user experience.
