HDR to SDR v3.1.2

What's new

New Target Bitrate mode alongside Constant Quality, selectable per file.
Each batch queue item now remembers and restores its own quality settings (mode, slider value, bit depth) when reselected or reloaded, instead of sharing one global value.
The info strip shows the probed source bitrate, including an estimate from the container total when a source (e.g. MKV) doesn't expose a per-stream bitrate.

Added an Apply to All button to copy the currently displayed settings onto every queued item.
The batch list now marks items with customized (non-default) settings, and the marker logic only compares fields relevant to the active quality mode.
Fixed the batch list losing the highlighted row after a click, and debounced list rebuilds while dragging the gamma/quality sliders.

Apply to All is now correctly disabled for free users, matching the other batch queue buttons.
Quality mode resets to Constant Quality if a Pro license lapses, instead of silently staying on Target Bitrate.
GPU-off state now persists correctly after a CPU fallback retry, instead of only living in memory.
Fixed the quality slider and Target Bitrate value getting corrupted when restoring a batch item's saved settings.
The preview window no longer shrinks and regrows while a new preview loads.

The displayed source bitrate can read about 6% higher than what Windows reports for the same file.
Re-converting a batch queue item that already completed successfully will instantly report "done," because the output file already exists on disk at that path from the prior run.
