… KDoc (#23791) (#23823) Splits the two contracts that PR #22535 (7.18.0) conflated: - decode() stays strict and Jackson-bound (@JsonCreator entry point) - decodeOrNull() is added as a lenient counterpart for direct callers that prefer the pre-7.19.0 null-on-unknown behavior This gives users impacted by the 7.19.0 change a trivial migration path (MyEnum.decode(x) -> MyEnum.decodeOrNull(x)) without giving up the Jackson safety fix or matching the kotlin-spring/Java client behavior. Also corrects the KDoc on decode() which still claimed "null otherwise" even though the function now throws.

Fixes #22534
Adds Jackson annotations to Kotlin client enums so numeric values are deserialized by value (not ordinal), and includes a regression test + spec repro for issue #22534.
