Steps to reproduce
------------------
1. On a bank payment method, enable "Identify Customer".
2. Create a lot of orders paid with this method and invoice them (the customer reporting the issue had 2081 orders).
3. Close the session.

The close takes several minutes, and on a remote database the request is killed by the worker time limit before it completes.

Cause
-----
`_reconcile_account_move_lines` reconciles each group of lines with its own `reconcile()` call, one per payment. Every call creates its partials and triggers the recompute cascade of the ORM, which searches `account.move.line` over the whole set of payments of the session, so the cost of a single call grows with the number of payments.

`_create_invoice_receivable_lines` has the same shape: the values are grouped per payment, so every group holds a single value and the lines are created one `create()` call at a time.

opw-6242303 already batched the creation and the posting of the split bank payments, and the reconciliation of their receivable lines, but only for the orders that are not invoiced. Invoiced orders go through `split_inv_payment_receivable_lines`, which was left untouched.

Fix
---
Gather every reconciliation of the session into a single `_reconcile_plan` call. The entries of the plan are processed independently and in order, so the result is the same as reconciling them one by one, but the recompute cascade runs once instead of once per payment.

Create all the invoice receivable lines in a single `create()` call and dispatch the records back to their payment method or payment afterwards.

Benchmark
---------
Closing a session of 2081 invoiced orders on a copy of the customer database:
- before: 558s
- after: 54s

### Steps to Reproduce:
1). Install l10n_vn_edi_viettel ('Vietnam E-Invoicing') module in v18. 
2). Migrate the database in any version above v18. 
3). AccessError will appear while generating ('Send to SInvoice') on invoice for non-admin users.

### Issue:
- In v18, users were able to send and generate documents via (Send to SInvoice). Since v18.1 onwards, field access [check] is enforced during this flow, and since `l10n_vn_edi_username` is restricted to admin users only [here], non-admin users hit an AccessError as soon as
`_l10n_vn_edi_get_credentials_company` reads this field on`res.company`.

```py
You do not have enough rights to access the field "l10n_vn_edi_username" on Companies (res.company). Please contact your system administrator.

Operation: read
User: 12
Groups: allowed for groups 'Role / Administrator'
```

### Solution:
- This commit fixes the issue by adding a `sudo()` call on the company inside [_l10n_vn_edi_get_credentials_company] itself, so that non-admin users can successfully send and generate documents like in the previous version, without any hassle.

Due to this issue, generating PDF Quote using Quote Builder with dynamic fields leads to a traceback.

This was partially fixed by: e16edc7b0d9f56cb7769068ecf7d64ff8b0f6359

Steps:
---
1- Using a python 3.13 env, install requirements.txt. (You could instead uninstall pypdf2 and install pypdf==5.4.0)
2- Enable Quote Builder.
3- Create a SO and in quote builder tab, select a document. This document should have dynamic fields. e.g. you could use`Office Furnitures Header` document.
4- Print -> PDF Quote.

Cause:
---
In previous fix, we fixed the traceback when no dynamic field is set. However, if you have a dynamic field, then inside
`PdfWriter._update_field_annotation()`, the font is get from `DR` dict inside acroform:
https://github.com/py-pdf/pypdf/blob/f20954f2241640feb484800e191373f8fbdfa44b/pypdf/_writer.py#L917-L929
Even if we are not setting a font, we need to have an empty `DR` dict inside acroform, in order to avoid calling `get` on a none object, which is leading to the traceback.

Also in previous fix we were losing `NeedAppearances` inside `AcroForm` by creating new dict which wasn't right.

### Description of the issue/feature this PR addresses:
Fixes an issue where timesheets lose their invoice reference when reversing and re-creating an invoice via a credit note.

### Current behavior before PR:
When reversing an invoice tied to timesheets and creating a replacement via a credit note, the timesheets linked to the original invoice have their timesheet_invoice_id cleared. Because the modify_moves function builds the replacement invoice directly via copy_data()/create(), it bypasses the normal sale order invoicing flow. As a result, the unbilled timesheets are left permanently unlinked from the newly created invoice, leaving the new invoice with no reference to the timesheets linked to the original sale order.

### Desired behavior after PR is merged:
When a replacement invoice is created, each timesheet is properly relinked to the corresponding line on the new invoice. This linkage matches on the sale order line (so_line) rather than line position, ensuring accuracy since line order and count are not guaranteed to be preserved between the original and modified invoices.

Step to reproduce:
 - create a faulty token that won't work and link it to a subscription
 - launch the recurring invoice cron
 - the following traceback occurs

```
last_tx_sudo = (self.transaction_ids - existing_transactions).sudo()
```

When the payment fails, the system rollback and we store the last_tx_sudo value in a dedicated variable. After rollback, the record does not exists anymore. Therefore, accessing the value fails.

Moreover, since https://github.com/odoo/enterprise/pull/45236/files#diff-c36fd7952cc2bef40716419a668de41963d49e1aa4177d9319d503fc260da588R1678-R1682

```
if not last_tx_sudo or not last_tx_sudo.renewal_state not in ['pending', 'authorized']:
```

has become

```
if not last_tx_sudo or last_tx_sudo.renewal_state in ['pending', 'authorized']:
```

But it feels strange to unlink the invoice when the payment succeed.


This PR fixes it.
