fix(audible): use expected URL patterns for product links

[imnotjames]

Description

Audible external URIs seem to require /pd/ instead of /dp/ like Amazon.

Linked Issue

related to #2316

Changes

Updates the audible external URI helper to emit URIs with /pd/

Manual Testing Steps

1. search on audible for "How to Talk to Your Cat About Gun Safety"
2. click "Audible" link
3. See audible URI as expected

Screenshots (Optional)

Additional Context (Optional)

This may have been mixed up because of the similar amazon change being made

**/*: This project is being developed using current and future-facing technologies:

• Java 25 with --enable-preview (preview features are INTENTIONAL and encouraged)
• Spring Boot 4 (latest major version, check APIs accordingly)
• Jackson 3 (new package: tools.jackson.* instead of com.fasterxml.jackson.*)
• Hibernate 7.3.x (Jakarta Persistence 3.2, new APIs; avoid deprecated Hibernate 5/6 patterns)
• Angular 21 (signals-based reactivity, no NgModules unless legacy)

Grimmory Internal Tools

• epub4j and pdfium4j are our own internal tools developed by the Grimmory team.
• Always verify behavior and API changes against the upstream repositories:
  • epub4j: https://github.com/grimmory-tools/epub4j
  • pdfium4j: https://github.com/grimmory-tools/pdfium4j
• If you encounter issues with these libraries, check if a fix exists in the upstream grimmory-tools organization.

Metadata Standards and Compliance

• For all metadata writing and parsing logic, double-check against Dublin Core and ANSI standards to ensure perfect official compliance.
• We strictly follow the widespread and official XML-compliant methods for EPUB2, EPUB3, CBX, and PDF formats.

General Java and Spring rules

• ALWAYS prefer modern, idiomatic Java 25 constructs over legacy patterns.
• Preview features (--enable-preview) are enabled and intentional; do NOT flag them as risky unless there is a concrete runtime issue.
• Prefer: records, sealed classes/interfaces, pattern matching (switch expressions, instanceof), structured concurrency (StructuredTaskScope), scoped values, string templates, unnamed patterns/variables.
• Prefer virtual threads (Thread.ofVirtual(), Executors.newVirtualThreadPerTaskExecutor()) over platform threads for I/O-bound work.
• Prefer the new Sequenced Collections API (SequencedCollection, SequencedMap) where applicable.
• Prefer var for local variables when the type is obvious from context.

Learning: When using Spring `ContentDisposition.builder(...).filename(name, StandardCharsets.UTF_8).build()` (i.e., explicitly providing UTF-8), the resulting header value should include both the quoted `filename="=?UTF-8?..."` and the RFC 5987 `filename*=` parameters. In this case, any extra ASCII fallback computation (e.g., deriving an ASCII `fallbackFilename` via `NON_ASCII_PATTERN` and calling `.filename(fallbackFilename)`) is likely redundant—prefer calling only `.filename(fallbackName?, StandardCharsets.UTF_8)` as appropriate and let Spring handle the UTF-8 header parameters. Verify by comparing the emitted header for `filename` and `filename*` before deciding to keep an ASCII fallback.

Learning: For this codebase (booklore-api), target Java 25 with `--enable-preview`, so `_` is intentionally used as an unnamed/ignored variable (e.g., lambda parameter or pattern variable) per Java’s preview feature JEP 456. Do not flag `_` in those contexts as an invalid/reserved identifier; only flag it if it’s used in a non-supported position (e.g., where an unnamed variable is not applicable for the Java preview rules).

Learning: For this repository, reviewers should treat string truncation done via `String.length()` and `String.substring(0, maxLength)` (UTF-16 code units) as an accepted, consistent convention. Do not flag individual occurrences of this pattern as bugs, even though it is not code-point-aware for surrogate pairs. A separate global effort is already tracked to move toward code-point-aware truncation, so per-site fixes should be avoided during code review.

Learning: In this repo’s Java code, when catching Jsoup `org.jsoup.HttpStatusException` (and similar exceptions originating from external libraries) and wrapping/rethrowing them, do not require preserving the original exception stack trace (e.g., as flagged by PMD `PreserveStackTrace`) as long as the application already captures the actionable diagnostics in logs or the thrown exception message (such as HTTP status code and the requested URL). Reviewers should still ensure the log/message contains those details; the intent is to avoid noisy stack traces that only reflect external-library internals rather than application code.

Learning: In this codebase (grimmory-tools/grimmory), it’s intentional to omit per-request timeouts on individual Java HttpRequest.Builder instances (e.g., GoodReadsParser.fetchJson). During reviews, do not flag missing builder-level timeouts as a best-practice violation; rely on framework-level and/or HttpClient-level timeouts configured elsewhere for consistent behavior. Only raise an issue if you can verify that no effective timeout is configured at the HttpClient/framework level.

Learning: In this codebase (grimmory-tools/grimmory), reviews should not treat inline `LIMIT`/`OFFSET` clauses inside `Query` JPQL/HQL strings as a JPA compliance risk. This is intentional: `hibernate.jpa.compliance.query=true` is intentionally not set, and Hibernate 7.3+ supports `LIMIT`/`OFFSET` as valid HQL extensions. Therefore, do not flag or require changes to `Query` annotations solely due to `LIMIT`/`OFFSET` usage.

Prefer letting the global exception handler translate it into a generic 5xx response rather than throwing an explicit ApiError 4xx (e.g., do not convert overflow into a client error).

Learning: In this repository’s JUnit 5 test sources (e.g., under backend/src/test/java/), do not flag “bare” `assert` statements as a bug. The project test runner is configured to always execute tests with assertions enabled (e.g., `-ea`), so `assert` behavior is consistent. Continue to review for correctness, but don’t treat unguarded `assert` usage in test classes as a static-analysis issue.

Learning: In backend unit tests (Java files under backend/src/test/java), do not flag hardcoded placeholder filesystem paths (e.g., setting LibraryPathEntity.path = "/example") as violations when the value is intentionally unused for filesystem access. Only suppress the "no hardcoded paths" concern if the test does not perform any filesystem/network IO using that path (no reads/writes/Files.* calls or code paths that access the filesystem with that value); if the placeholder is actually used to touch the filesystem, flag it.

Learning: In grimmory-tools/grimmory unit/integration test classes (e.g., files matching **/*Test.java under backend/src/test/java/**), it is acceptable to directly instantiate Jackson mappers (e.g., `new ObjectMapper()` / `new JsonMapper(...)`) and this should NOT be flagged. The Jackson guidance to use Spring bean injection or `JsonMapper.shared()` applies only to production code; tests may construct dependencies directly as standard practice. Production-code mapper instantiation rules should still be enforced outside test sources.

Audible product URLs now use the /pd/{asin} path. Tests update the Japanese and default URL expectations. Null ASIN handling remains unchanged.

Merge Risk: 🟡 Moderate · up to 7137d

The PR currently generates Audible product links with the wrong path, which can send users to incorrect product URLs. Merge is not ready until the implementation and related assertions use /ac/{asin}; the issue is localized and straightforward to correct.
