Deivid Soto 0f4ad67827 fix(transcode): make preset libx264-only + restore quality opt-in
Two issues with the 0.9.9 preset retune:

1. applyDefaults was filling Preset="veryfast" before
   ResolveEncoderProfile got to pick the latency-biased default, so the
   "superfast" change never reached users with a freshly-generated
   config.toml — only those who left the field empty saw it.

2. The configured preset was being passed through to every encoder.
   That's only valid for libx264 (ultrafast…veryslow); NVENC uses p1-p7
   and rejects anything else, QSV uses its own subset. A user with NVENC
   + preset="veryfast" would have ffmpeg reject the argv.

Now:
- TranscodeConfig.Preset documented as libx264-only with the full
  range + advice on quality vs first-start latency.
- Default in applyDefaults is empty (was "veryfast") so the engine
  fills in "superfast" on libx264.
- ResolveEncoderProfile ignores configuredPreset for vendor encoders
  (NVENC sticks to p3, QSV to veryfast, VideoToolbox has no preset
  knob). Test cases updated to lock in this behaviour.

Users who want better quality at slower first-play should set
download.transcode.preset = "veryfast" (previous default) / "faster" /
"fast" / "medium" in their config.toml.
