This update streamlines how users see and move to the next status for account returns, making the workflow clearer. Audit-related returns are now automatically marked complete after validation, reducing manual follow-up.

* Simplify the view logic for displaying the state transition buttons by adding a new computed field for the next_state of current return type.

* For Audit category return, automatically set is_completed to True after validation.

The Point of Sale due payment flow no longer loads all account move records upfront when opening the interface. This reduces memory use and loading times, making the experience faster and more reliable for users handling settlements.

Before this commit, all account.move records were loaded into the PoS interface, even though they were not used immediately. This caused significant performance issues, increasing memory usage and loading times.

Odoo Studio’s report editor has been improved so users can edit existing dynamic fields directly in reports. The underlying editor tools were reorganized to make the report editor easier to maintain and test, supporting more reliable future improvements.

Fixes a reconciliation issue where currency conversions with many decimal places could create small artificial differences, such as one cent. The system now keeps the original foreign currency amount when the recalculated value is close enough, helping invoices reconcile correctly and reducing manual follow-up.

The aim of this commit is to keep the original foreign amount currency
if the computation ends up close enough to it.

Before this commit:
The reconciliation process was losing so much precision that it could mess up
the reconciliation of one single invoice.

After this commit:
We keep the original amount as it is most probably the correct one.

Context:
With a rate of 1 US$ = 5.421327349 R$ and an invoice of 143.62 R$, we
convert the amount in US$ which is 26.491668921649627 US$.
As we have to round it for the accounting, we end up with 26.49 US$ as
company currency amount, losing the rest of the decimals.
During the reconciliation process, we convert back the US$ to R$ ending
up with 143.61096147501 R$ that have to be rounded to 143.61 R$.

This creates a difference of 0.01 R$ which surfaces later on.

Chosen solution:
As we still have the original currency amount and the rate, we are able
to recompute the raw numbers and we are able to make "fairer" comparison
between the amounts.
If we can confidently tell that the amounts are close enough, we
can just keep the original amount and prevent all those rounding errors
to be taken into account.

This update fixes issues that could prevent AI live chat conversations from being found correctly, especially for website visitors. It also keeps the AI live chat status accurate when a conversation is transferred to a human operator, reducing broken or confusing chat experiences.

This commit solves the following bugs:

- Update the logic of retrieving ai chat channel to include livechat channels.

- Given that retrieving ai chat channel relies of `is_member` being True, the value of the `mail.guest` record corresponding to the current user (in case of public users) should be added to the context.

- The value of `livechat_with_ai_agent` wasn't synced when the livechat channel was forwarded to a human operator. This caused bugs in the ai livechat snippet.

Applying a commission or partnership grade to a company contact will no longer automatically apply it to related child contacts. This restores the intended behavior and helps avoid incorrect commission or subscription partnership settings being assigned across linked contacts.

This reverts commit 14001a8a0216750be0c897d0e1bf31fccfc51c6a so that applying a grade no longer adds it to the children of the partner as well.
