During the rework of the follow-up report, we removed the
"No Follow-Up" field from journal items, making it impossible to exclude
individual journal items from triggering a follow-up.

In this commit we do the following:
-  Re-introduce a field for that, since it is a common
   requirement to be able to exclude individual items from the follow-up
   reports.
   The field is stored on the journal item, but can also be toggled from
   the journal entry. In case of multiple installments on the invoice,
   toggling the field on one installment will toggle it for all
   installments.
-  Adapt the Follow-Up Report and Customer Statement variants of the
   Partner Ledger to add a toggle for the "No Follow-Up" field on each
   report line, that toggles the field on the corresponding journal
   item(s).
-  Prevent the follow-up status on the partner to change when all of the
   overdue journal items are marked as "No Follow-Up".
-  Make sure users can toggle the "No Follow-Up" setting on the invoice
   level when opening the "Overdue Invoices" view from the partner's
   "Accounting" tab.
-  Make sure all receivable/payable lines without a due date (either
   from a manual miscellaneous entry or a PoS entry) are put under the
   "Due" section in the Follow-Up Report instead of the "Overdue"
   section. Since there is no due date, they can't be overdue.
-  Make sure the PDF and XLSX exports of the Follow-Up Report don't
   include the "No Follow-Up" lines, and the customer follow up email
   only includes the amount of the other lines.
