When a Bulgarian VAT return is validated, Odoo now automatically generates and attaches the required monthly SAF-T general ledger, purchase, and sales report files alongside the PDF. This helps large companies meet Bulgaria's monthly tax reporting requirements with less manual work, and the related download error messages are easier to understand.

Bulgaria made it mandatory for large companies to present a monthly file
to report their VAT to the administration. To streamline that process,
when the VAT return is validated and PDF is added to the attachments, 
the monthly General Ledger SAF-T file, the POKUPKI Purchase Report and 
PRODAGBI Sale Report are produced and added as well.
 
Simplify the report file download error wizard's visuals and descriptions to improve readability.

Cached website generation requests now schedule a quick follow-up task instead of calling webhooks immediately. This helps ensure notifications happen after the generation work is safely saved, without tying up system workers unnecessarily.

When a request is cached a webhook won't be called because if we did it immediatly it might arrive before the generator commited. And we don't want to delay the webhook call to not stall a worker just for that.

So we simply scheldule a trigger if a request was cached.

Before this commit:

- Refund orders of scheduled (with shipping date) orders always generated a new picking with negative quantities, even when the original delivery had not been completed.
- This could lead to incorrect stock movements and negative quantity computations for undelivered pickings.

After this commit:

- When processing a refund of a scheduled (with shipping date) order, the behavior now depends on the state of the original picking:
  - If the picking has already been delivered, a return picking is created with the corresponding negative quantities.
  - If the picking has not been delivered, the original picking is updated instead:
    - The picking is cancelled for a full refund.
    - Refunded product moves are removed from the picking for a partial refund.
- This prevents unnecessary negative stock movements and ensures stock operations remain consistent with the delivery status.
