Crash on muxing MP4 with ADTS AAC audio ("Malformed AAC bitstream detected")

## Describe the bug

When processing an MP4 file containing AAC audio with ADTS headers, the encoding/muxing step crashes with a PermissionError and stops the pipeline.

Last error log from FFmpeg: `[mp4] Malformed AAC bitstream detected: use the audio bitstream filter 'aac_adtstoasc' to fix it ('-bsf:a aac_adtstoasc' option with ffmpeg)`

## To Reproduce

GUI processor running a video job with an AAC/ADTS audio stream.

## Desktop (please complete the following information)

OS: Windows 11 25H2

Jasna Version: 0.10.0

GUI or CLI? GUI

GPU: NVIDIA GeForce RTX 5080

Nvidia Driver version: 615.56

CPU: 9800X3D

## Suggested improvement

I suggest adding an automatic detection and conversion step for this case.

When Jasna detects an AAC audio stream with ADTS headers and the target container is MP4/MOV, it could automatically apply the `aac_adtstoasc` bitstream filter before muxing.

This should allow the AAC stream to be converted to the format required by the MP4 container without re-encoding the audio, avoiding both quality loss and unnecessary processing overhead.

Ideally, this could be handled during a preflight/media analysis stage so the incompatible AAC bitstream is detected and corrected before the encoding/muxing stage, rather than causing the encoder worker to crash.
