Generate DANFSE locally from authorized XML

[vitormattos]

Summary

• pin librecodeoop/nfse-php to the upstream revision that includes local DANFSE generation support
• update InvoiceController to generate DANFSE locally from the authorized NFS-e XML instead of routing through the client transport path
• align the focused DANFSE controller tests with the local XML-based generation flow
• update the transport cleanup regression test to assert the HTTP client DANFSE path is not used during artifact storage

How to test

1. Run the focused DANFSE controller tests:
   • docker compose exec -u www-data akaunting.php sh -lc 'cd /var/www/html/modules/Nfse && php vendor-bin/phpunit/vendor/bin/phpunit --filter "testStoreArtifactsPersistsXmlEvenWhenDanfseFails|testGenerateDanfseFromAuthorizedXmlUsesReceiptRawXml|testStoreArtifactsPersistsPdfWhenDanfseGenerationSucceeds|testStoreArtifactsGeneratesDanfseLocallyWithoutUsingClientTransport" tests/Unit/Http/Controllers/InvoiceControllerTest.php tests/Unit/Http/Controllers/TransportCertificateCleanupTest.php'
2. Confirm the tests pass.
3. Optionally verify that 3rdparty/scoped/librecodeoop/nfse-php/src/Danfse/ exists after the scoped dependency refresh.
