Save As JPEG: JPEG Options dialog (quality 0–12, Baseline / Optimized / Progressive) (FILE-215-19)

Save As and Save a Copy to a JPEG now ask for JPEG Options before writing,
as Photoshop does. Re-creates #4330 on current main and folds in the
unique parts of #5580 (#5563).

- codecs: `JpegFormat` (Baseline, Optimized, Progressive) on
  `EncodeOptions`. Progressive writes SOF2. Baseline Optimized fits the
  Huffman tables only at 4:4:4 (Gray, CMYK) or with Progressive: fitted
  tables make the baseline scans non-interleaved, which zune-jpeg 0.5.15
  decodes wrongly with 4:2:0 chroma (zune-image#419), as Save for Web
  already works around.
- engine: a `jpegFormat` save param (file.saveACopy, Batch, Image
  Processor, Layers to Files and every SaveOpts user; anything but the
  three names is BadParams before writing) and a shared 0–12 -> 1–100
  `jpeg_quality()` that maps NaN/inf to 100.
- ui-egui: `jpeg_options_ui` (Quality 0–12 with Low/Medium/High/Maximum
  presets, Format Options), parked like Targa Options. It starts at the
  opened JPEG's own quality (`file_encoding`, #4032), else the Export
  preference; left there, OK writes that quality exactly and the step
  records no `quality`. `SaveChoices` (Targa bits + JPEG) replaces the
  bare `tga_bits` through file.save / file.saveAs / app.save, replay and
  Save a Copy; automation never prompts. `write_answered_save` is shared
  with Targa Options. `park_at` + `Start` let any save seed the prompt.
  A File › Save that confirms the document's own flat JPEG is still
  journalled as a plain `file.save` (#3531).
- CLI: `--jpeg-format`.
- i18n: five new strings in all 20 catalogs (#4330's duplicate de/es/zh
  `Low`/`High` rows dropped: main has them since #4008).
- Docs: book raster-formats JPEG bullet, control protocol, file-format
  parity, gaps G10, target-app parity; scorecard FILE-215-19 done.
