Honor PropertyNamingStrategy for get/is-prefixed property names

[seonwooj0810]

Description

When a custom PropertyNamingStrategy (e.g. SNAKE_CASE) is configured on the mapper, ModelResolver produced inconsistent schema property names: most fields were translated, but any property whose member name starts with a get/is prefix followed by a lower-case letter kept its original camelCase name.

Example (SNAKE_CASE, Java record):

public record PidLookupResponse(
    String familyName, String expiryDate,
    String issuanceDate, String issuingCountry, String issuingAuthority) {}

Produced:

family_name, expiry_date, issuanceDate, issuingCountry, issuingAuthority

instead of the expected issuance_date, issuing_country, issuing_authority.

Root cause

The "avoid clobbering properties with get/is names" hack (added for #415) overwrites the Jackson-resolved property name with the raw member name whenever the member name starts with get/is + lower-case. For record components the accessor's physical name is the bare component name (issuanceDate), which starts with is, so the hack replaced the strategy-translated issuance_date with issuanceDate.

Fix

Only apply the hack when no PropertyNamingStrategy is configured. When a strategy is active the resolved name is authoritative and must be honored uniformly. The hack was only ever needed to restore raw names in the absence of a strategy:

• Play2/scala: A property named "is_persistent" gets shortened in the json to "_persistent" #415 (Scala accessor is_persistent wrongly shortened to _persistent) — default mapper, no strategy → hack still runs.
• @XmlElement(name="myName") not honored for fields starting with "is" #2635 (JAXB-renamed is-prefixed fields keeping their original name) — JAXB mapper, no strategy → hack still runs.

Both existing test cases continue to pass.

This bug surfaces through springdoc and was traced to swagger-core: springdoc/springdoc-openapi#3293.

Test evidence

Added RecordPropertyNamingStrategyTest (in swagger-java17-support, which compiles at Java 17 for records). It fails on master (issuanceDate not translated) and passes with this change.

Verification done: reproduced on master; ran the full test suites for swagger-core, swagger-jaxrs2 (incl. ReaderTest#testModelResolverXMLPropertiesName for #2635) and swagger-java17-support — all green (BUILD SUCCESS).
