## Description Fixes thread accumulation issue in [applicationEventMulticaster](cci:1://file:///home/deathgun/fineract/fineract-provider/src/main/java/org/apache/fineract/infrastructure/core/config/SpringConfig.java:33:4-38:5) caused by `SimpleAsyncTaskExecutor` creating unbounded threads. ### Problem The existing `SimpleAsyncTaskExecutor` creates a new thread for every event, leading to thread exhaustion under load (200+ concurrent users). This causes JVM memory exhaustion and service outages. ### Solution - Replace `SimpleAsyncTaskExecutor` with bounded [ThreadPoolTaskExecutor](cci:1://file:///home/deathgun/fineract/fineract-provider/src/main/java/org/apache/fineract/infrastructure/configuration/async/SpringAsyncConfig.java:32:4-37:5) - Core pool: 20 threads, Max pool: 100 threads - Add `DelegatingSecurityContextAsyncTaskExecutor` wrapper for security context propagation - Graceful shutdown with task completion wait ### Testing - Application starts successfully - Events processed on `FineractEvent-*` thread pool - No thread accumulation observed ## Checklist - [x] Write the commit message as per [our guidelines](https://github.com/apache/fineract/blob/develop/CONTRIBUTING.md#pull-requests) - [x] Acknowledge that we will not review PRs that are not passing the build _("green")_ - [x] Create/update [unit or integration tests](https://fineract.apache.org/docs/current/#_testing) for verifying the changes made. - [x] Follow our [coding conventions](https://cwiki.apache.org/confluence/display/FINERACT/Coding+Conventions). - [x] Add required Swagger annotation and update API documentation (N/A - no API changes) - [x] [This PR must not be a "code dump"] -- This is an automated message from the Apache Git Service.
