[18.0][FIX] mis_builder: account.account has company_ids in Odoo 18

[StefanRijnhart]

Adapted from https://github.com/OCA/mis-builder/pull/711, but observing that in Odoo 18, there is no company_id field anymore, and the company_ids field is required, thus removing several test cases.

Limit display to 3 companies plus ellipsis.

Fixes

  File "/home/odoo/mis-builder/mis_builder/models/kpimatrix.py", line 478, in _get_account_name
    result = f"{result} [{account.company_id.name}]"
                          ^^^^^^^^^^^^^^^^^^
AttributeError: 'account.account' object has no attribute 'company_id'
