Remove unnecessary IOException declarations

[Copilot]

Description

Removes throws IOException declarations from methods that don't perform I/O operations. Cleans up redundant exception declarations where subclasses are unnecessarily listed alongside parent exceptions.

Resolves #[issue number]

Changes

• Test methods (14 files): Removed throws IOException from methods that only call toString(), builders, or assertions
• Sample application: Removed redundant FileNotFoundException from method already declaring IOException

Example

Before:

@Test
void whenCallingToStringThenResultIsExpected() throws IOException {
    final var result = account.toString();
    assertThat(result, is("Account(...)"));
}

After:

@Test
void whenCallingToStringThenResultIsExpected() {
    final var result = account.toString();
    assertThat(result, is("Account(...)"));
}

What Remains

All Jackson serializer/deserializer methods correctly retain throws IOException as required by their parent interfaces. Test methods performing actual I/O operations (JSON parsing, file reading) remain unchanged.

Checklist:

• Public methods are documented
• Public methods are tested
• New and existing tests pass when run locally
• There are no new warnings or errors

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkstyle.org
  • Triggering command: /opt/hostedtoolcache/CodeQL/2.23.3/x64/codeql/tools/linux64/java/bin/java -jar /opt/hostedtoolcache/CodeQL/2.23.3/x64/codeql/xml/tools/xml-extractor.jar --fileList=/home/REDACTED/work/xapi-java/.codeql-scratch/dbs/java/working/files-to-index14034589272145833435.list --sourceArchiveDir=/home/REDACTED/work/xapi-java/.codeql-scratch/dbs/java/src --outputDir=/home/REDACTED/work/xapi-java/.codeql-scratch/dbs/java/trap/java (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

This section details on the original issue you should resolve

<issue_title>[Enhancement]: Remove unnecessary 'java.io.IOException' thrown declarations</issue_title>
<issue_description>### What

Remove the declaration of thrown exception 'java.io.IOException' in all places (methods, signatures, etc.) where it cannot actually be thrown from the method's body. This means updating method signatures and implementation to only declare 'java.io.IOException' where it is relevant and possible for the exception to be thrown.

Why

Cleaning up unnecessary exception declarations improves code readability and maintainability. It eliminates confusion during development and helps prevent misleading exception handling, ensuring that exception signatures accurately reflect possible runtime behaviors.
