   ## Description
   
   `HookReadPlatformServiceImpl.retrieveHooksByEvent(entityName, actionName)` is `@Cacheable` with the key `<tenantId>HK`. With an explicit `key`, Spring ignores the method arguments, so every event in a tenant shares one cache entry, but the result depends on both arguments (`HookRepository.findAllHooksListeningToEvent` filters on `entityName` and `actionName`).
   
   `FineractHookListener` calls it after every write command. So when the "hooks" cache is live, the first command in a tenant fills the entry and, until it expires (default TTL 1 minute) or a hook is changed, every other event gets that same list. Example: hook A listens to CLIENT/CREATE and hook B to LOAN/APPROVE. A client is created first; for the next minute, approving a loan fires A with the loan payload and B never fires. If the first command is one no hook listens to, the entry is an empty list and no hook fires for any event in that window.
   
   The cache is only live when the tenant uses the single-node cache (`PUT /caches` with `cacheType: 2`). The default cache type gives "hooks" a no-op cache, which is why default installs and the existing hook integration tests do not see this.
   
   The key now includes the event: `<tenantId>HK|<entityName>|<actionName>`. The tenant is still in the key, and the hook create, update and delete commands already evict all entries (`@CacheEvict(allEntries = true)`), so nothing else changes.
   
   Added `HookReadPlatformServiceImplCacheTest`, which runs the service through a real Spring cache (`@EnableCaching` with a `ConcurrentMapCacheManager`) and a mocked `HookRepository`:
   - `secondEventDoesNotGetTheHooksCachedForTheFirstEvent`: CLIENT/CREATE then LOAN/APPROVE, each gets its own hooks.
   - `hooksAreStillCachedPerEvent`: calling each event twice reads the repository once per event.
   
   Both fail on develop (LOAN/APPROVE gets the CLIENT/CREATE hook) and pass with this change.
   
   Side note, not changed here: the cached values are `Hook` JPA entities, which outlive the transaction that loaded them. Happy to look at that separately if you think it matters.
