Add multi-author APA citation test case

• Adds testEntry2 field initialized with TestEntry.getTestEntryBook() for multi-entry testing
• Fixes aPACitation() test to use correct "APA Style 7th edition" style filter instead of "ACM
 SIGGRAPH"
• Updates expected output in aPACitation() from "[Smith et al. 2016]" to "(Smith et al., 2016)"
 for correct APA format
• Adds new aPACitation2Authors() test method that validates citation generation with multiple
 bibliography entries

Description

The new variable name testEntry2 is a non-meaningful placeholder, making the test harder to read
and maintain. This violates the naming guideline that forbids typos/placeholder patterns like
...2/extraEntry2.

Code

jablib/src/test/java/org/jabref/logic/citationstyle/CitationStyleGeneratorTest.java[39]

+    private final BibEntry testEntry2 = TestEntry.getTestEntryBook();

Evidence

PR Compliance ID 13 requires meaningful, correctly spelled variable names and explicitly calls out
placeholder patterns (e.g., extraEntry2). The PR introduces testEntry2 and uses it in the new
test, which is a placeholder-style name rather than intention-revealing (e.g., bookEntry,
secondEntry, harrerEntry).

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The test introduces a placeholder-style variable name (`testEntry2`), which reduces readability.
## Issue Context
The project naming guideline requires intention-revealing names and explicitly discourages placeholder suffix patterns like `...2`.

Description

In aPACitation2Authors, generateCitation is called with two BibEntry objects but the provided
BibDatabaseContext’s BibDatabase contains only testEntry. This can change resolved-field behavior
(e.g., crossref/string resolution) for testEntry2 and makes the test less representative of real
usage.

Code

jablib/src/test/java/org/jabref/logic/citationstyle/CitationStyleGeneratorTest.java[R79-81]

+        String citation = CitationStyleGenerator.generateCitation(List.of(testEntry, testEntry2), style.getSource(), HTML_OUTPUT_FORMAT, testEntryContext, ENTRY_TYPES_MANAGER);
+
+        String expected = "(Harrer et al., 2018; Smith et al., 2016)";

Evidence

The test’s context database is constructed with only testEntry, while the citation generation
includes testEntry2 as well. CSL conversion resolves field values via
BibEntry.getResolvedFieldOrAlias using the BibDatabase from the provided BibDatabaseContext;
crossref and string resolution depend on the database contents, so omitting testEntry2 can produce
different resolved values than a real database containing both entries.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`aPACitation2Authors` passes `List.of(testEntry, testEntry2)` to `generateCitation`, but `testEntryContext` is built from a `BibDatabase` containing only `testEntry`. This can affect resolved fields (e.g., crossref and string resolution) and makes the test setup inconsistent.
## Issue Context
`JabRefItemDataProvider` resolves fields via `bibEntry.getResolvedFieldOrAlias(key, bibDatabaseContext.getDatabase())`. `BibEntry#getResolvedFieldOrAlias` uses the provided database for string resolution and to follow `crossref` links.

- jablib/src/test/java/org/jabref/logic/citationstyle/CitationStyleGeneratorTest.java[75-84]
## Suggested fix
In `aPACitation2Authors`, create a dedicated `BibDatabaseContext` that contains *both* entries (e.g., `new BibDatabase(List.of(testEntry, testEntry2))`) and use that context for the call. This avoids changing shared test state for other tests while making the multi-entry test realistic.

Description

The method name aPACitation2Authors suggests it tests “two authors”, but it actually tests citing
two different entries in one combined citation. This can mislead future maintenance and weaken
understanding of coverage.

Code

jablib/src/test/java/org/jabref/logic/citationstyle/CitationStyleGeneratorTest.java[76]

+    void aPACitation2Authors() {

Evidence

The test passes two BibEntry instances to generateCitation (two works in one citation), so the
behavior under test is multi-entry/multi-citation formatting rather than a single-entry ‘two
authors’ case.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`aPACitation2Authors` is named like it validates a two-author scenario, but the test actually validates a combined in-text citation for two entries.
## Issue Context
The method calls `generateCitation(List.of(testEntry, testEntry2), ...)` and asserts the combined output.
## Fix Focus Areas
- jablib/src/test/java/org/jabref/logic/citationstyle/CitationStyleGeneratorTest.java[75-84]
## Suggested fix
Rename the test to something like `aPACitationMultipleEntries()` or `aPACitationTwoEntries()` (or similar) so the name matches what is asserted.
