fix: serialize cache values to fix Cacheable with serializable_classes (#588) (#589)

* fix: 🐛 serialize cache values to fix Cacheable with serializable_classes

When Laravel's `cache.serializable_classes` is set to `false` (or a
restricted array), PHP's `unserialize()` converts stored Eloquent models
into `__PHP_Incomplete_Class` objects, making cached results unusable.

ModelCacheRepository now wraps every stored value with a sentinel prefix
(`genealabs:lmc:v1:serialized:`) and explicit `serialize()`/`unserialize()`
calls, bypassing the driver-level `allowed_classes` restriction entirely.

The transparent `makeCacheDeserializeProxy` in test infrastructure
auto-deserializes values so existing tests need no per-call changes.

Closes #588

* test: ✅ verify serializable_classes=true and dedupe deserialization helper

Addresses tracer bullet review feedback on #589:

- Added test_cacheable_trait_works_when_serializable_classes_is_true to
  exercise the Cacheable trait under the actual restriction the bug
  reports. Existing tests set the config to false before caching, which
  never proved the fix. Updated the "under restriction" test to set
  serializable_classes=true *before* the cached calls.
- Extracted deserializeCacheValue helper on CreatesApplication so the
  prefix-detection logic lives in one place. DynamoDbModelCachingTest now
  calls the helper instead of duplicating the unserialize incantation.
- Verified ModelCacheRepository has no remember(\$ttl) method — only
  get/rememberForever/forever/forget — so all write paths are already
  covered by the prefix wrapping in PR #589.

* test: ✅ Brought all tests back to green.
