Original PR description

Steps to reproduce the bug:
- Install the l10n_mx_edi_landing module
- Go to inventory > Operations > Landed Costs
- Create a new landed cost > add product
- Do not fill the “customs number” field
- An error is triggered

Problem:
A constraint is checked for each landed cost, in which we try to directly access the 'l10n_mx_edi_customs_number' field without checking if it is filled.

Solution:
'l10n_mx_edi_customs_number' is an optional field, so we can add a verification to be sure it's filled before accessing it.

When selecting records on workorder list view, we can have next to
return button:

  "80 selected -> Select all 2921"

Clicking on that returns us to workcenter kanban view because the return
button was set over the whole button bar, not just the return button.

Remove fuzzy entries that are kept (while they should be ignored,
fuzzy entries are generated by closest match and often wrong) because
of pofile.merge. Update the es_MX.po file to keep only translated
terms.
