ruv a426ae386d Fix ADR-081 Timer Svc stack overflow on ESP32-S3 ...

emit_feature_state() runs inside the FreeRTOS Timer Svc task via the
fast loop callback; it memsets an rv_feature_state_t, queries vitals/
radio, and sends via stream_sender (lwIP sendto). Default Timer Svc
stack is 2 KiB, which overflows and panics ~1 s after boot:

  ***ERROR*** A stack overflow in task Tmr Svc has been detected.

Bump CONFIG_FREERTOS_TIMER_TASK_STACK_DEPTH to 8 KiB across the three
sdkconfig defaults files (default, template, 4mb). Matches the main
task stack size already in use.

Found during on-device validation on ESP32-S3 (MAC 3c:0f:02:e9:b5:f8)
after flashing the post-merge v0.6.1 build — firmware boots, connects
WiFi, emits one medium tick, then crashes on the fast tick that calls
emit_feature_state().

Follow-up: consider moving emit_feature_state + network I/O out of the
timer daemon into a dedicated worker task (open issue).
