[FIX] {account,l10n_eu_oss}_reports: ensure closing entries uses correct OSS report

Enterprisesaas-18.2accountl10n_eu_oss_reportsMedium

This update fixes an issue where closing entries for OSS reports were incorrectly generated as standard tax returns. The change simplifies a process that previously caused a mismatch in document types, ensuring that OSS reports are now correctly identified and processed after posting. This improves accuracy in financial reporting for EU VAT compliance.

### Issue:
When closing an OSS report, the generated tax closing entry was incorrectly identified as a standard Tax Return
After posting, the document type remained `Tax Return` instead of the expected OSS report type

### Cause:
In this PR: https://github.com/odoo/enterprise/pull/95775, a condition was simplified to unify closing moves across report variants However, this caused OSS reports to be treated as standard tax reports

As a result, only one closing move could be created and reused for both Tax Reports and OSS Reports for the same period The document was also incorrect because of this simplification

### Steps to reproduce:
- Install `l10n_nl` and switch to NL Company
- Activate `EU Intra-Community Distance Selling` in Settings (reload taxes if needed)
- Confirm invoices for a Belgian Customer using the tax 21% BE VAT
- Go in Accounting > Reports > Tax Return
- Select the report type OSS Sales and the quarterly period
- Click `Closing Entry`
- Post the entry A Tax Return document is created instead of an OSS report

### Other Fix:
If a standard Tax Report closing entry is created first, the closing move becomes linked to it and is then incorrectly reused for the OSS report
