Steps to reproduce:
- Post a Peruvian invoice so it is sent to SUNAT (directly or through Estela/Digiflow).
- SUNAT's sendBill call hangs and Odoo's request times out (ReadTimeout / ConnectionError), even though SUNAT actually finishes registering the document on its side a moment later.
- Odoo retries sending the same invoice (either automatically through the EDI cron, or manually). SUNAT now replies with a "document already exists" SOAP fault (code 1033/4000), since it processed the previous attempt.
- Odoo tries to recover from this by fetching the CDR through getStatusCdr, but SUNAT has not finished generating it yet, so the lookup also fails.

Cause of the issue:
_l10n_pe_edi_post_invoice_web_service() already has recovery logic for error codes 1033/4000: it calls _l10n_pe_edi_retrieve_cdr() to fetch the CDR and treat the invoice as sent. But when that lookup itself fails (CDR not generated yet), the resulting error keeps the 'blocking_level' set to 'error' from the original SOAP fault. Documents with blocking_level 'error' are excluded from the automatic EDI cron retries (see account.edi.document._cron_process_documents_web_services), so the invoice gets stuck needing a manual retry, which can lose the same race against SUNAT again and again.

Solution:
When the CDR can't be retrieved yet after a 1033/4000 duplicate error, mark the result as 'blocking_level': 'warning' instead of leaving it at 'error'. This keeps the invoice eligible for the automatic EDI cron retries, so Odoo keeps polling SUNAT until the CDR becomes available, instead of requiring manual intervention every time this race is lost.

mark_urbanpiper_prep_order_as_printed() raised ValueError when the
'urbanpiper_printed' flag was already set, to stop the same order from
printing its preparation ticket twice (https://github.com/odoo/enterprise/pull/103894,
Task-5353283).

Accepting an UrbanPiper order fires this RPC from two places for the
same order: synchronously from TicketScreen, and again via the
DELIVERY_ORDER_COUNT bus notification the accept flow itself
broadcasts. Under load, both requests race for the row lock; Odoo's
retrying() replays the loser on lock contention, and by the time it
replays the winner has already committed, so the loser hits the
already-printed branch and raises. The raise is an unhandled
ValueError, so it surfaces as a 500 and fails any tour that accepts
an order (test_frontend.py, test_order_receipt.py),
intermittently and CI-timing-dependent only.

The only caller (pos_store.js: _sendDeliveryOrderForPreparation)
already wraps the RPC in try/catch and treats a caught exception
exactly like a falsy return value: either way it just skips sending
the ticket to preparation. No other code reads or writes
urbanpiper_printed, and no webhook path calls this method, so
returning False is behaviorally identical for every real caller and
safe to make the default.

This also removes the mark_urbanpiper_prep_order_as_printed_patch
monkeypatch added alongside the original raise in test_01_order_flow:
it existed solely to swallow this exact ValueError for that one tour,
which is no longer needed now that the method itself is idempotent.

Since `company_id` on `worksheet.template` changed due to this a973d7d from a Many2many to a Many2one field.

For example, in v17, a single worksheet template linked to 3 companies via the m2m field was returned as 1 record when opening Design Template. After the upgrade in v18, company_id became m2o, and the same data is split into 3 separate records (one per company).

When trying to add a customization via Studio, the search [fetches](https://github.com/odoo/enterprise/blob/18.0/worksheet/controllers/main.py#L12) records based on the model set on the worksheet. In the new version, Studio
[creates](https://github.com/odoo/enterprise/blob/18.0/worksheet/models/worksheet_template.py#L112)
 a new model, but for existing records the
model is the same across the 3 worksheet records tied to the same template. This causes the search to match all 3 records and raise a SingletonError.

When attempting to refund orders that were created with the "Consumidor Final" customer. The refund validation would crash with a TypeError instead of showing the proper error message.

Steps to reproduce:
-------------------
In POS with l10n_ec_edi module activated:
* Create a new order with "Consumidor Final" as customer
* Add products and pay the order
* Validate the order
* Attempt to refund this order

> Observation:
The refund validation would crash with:
TypeError: Cannot read properties of undefined (reading 'add') at OrderPaymentValidation.isOrderValid

Why the fix:
------------
The code was trying to access `this.dialog` which is undefined in the OrderPaymentValidation class context. The dialog service should be accessed via `this.pos.dialog`, which is the correct pattern used throughout the base OrderPaymentValidation class. This fix ensures the error dialog is properly displayed when attempting to refund orders for the anonymous final consumer, instead of crashing with a TypeError.
