Subject: [PATCH] fix: bump engine_task default stack to 8192
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

4096 isn't enough for the DTLS-SRTP handshake — mbedTLS blows through
the stack during cert generation and triggers a FreeRTOS stack overflow.

Backtrace: dtls_srtp_selfsign_cert → dtls_srtp_init → peer_open → engine_task

8192 fixes it. Tested on ESP32-S3 with PSRAM.
