Rationale for this change

The encryption matrix omits AES_GCM_CTR_V1 with a plaintext footer. Cover this combination using Adam Reeve's shared C++ sample from apache/parquet-testing#130, alongside the Java writer's own round trip.

What changes are included in this PR?

• Add the configuration to the existing writer/decryption and interoperability matrices, including projection of plaintext columns without decryption properties.
• Pin the new sample to eedfad3f086678d282a00d8ff3cf8932d5d29af5. Keep the six existing samples at their current revision.
• Check the complete row count in both read paths. The shared samples contain 50 rows; adjust the expected data accordingly.

Are these changes tested?

On JDK 17, macOS ARM64:

• ./mvnw -pl parquet-hadoop verify -Dit.test=ITTestEncryptionOptions -Dmaven.javadoc.skip=true -Dsource.skip=true: 882 unit cases passed, 26 skipped; the encryption integration test passed.
• A valid zero-row replacement for the new shared file is ignored by the original suite. The extended suite fails with expected 50 / actual 0. Restoring the real sample passes.
• Spotless and RAT checks pass.

The zero-row control was local validation tooling and is not included in this patch.
