docs(i18n): resync the 9 translated manuals with the current English pages

[seto77]

Summary

Nine manual translations (de, es, fr, it, ko, pt, ru, zh-Hans, zh-Hant) had fallen out of sync with the English source. Several pages were still translations of the June–July English text, and later English corrections never reached them. The biggest one was the 2026-08-30 proofreading commit 346be81: in many languages it only changed notation, not the content. This PR brings all 9 languages back in line with the current English. English (en) and Japanese (ja) are not changed; Japanese was already in sync.

Pages rewritten from the current English

• 8. Electron trajectory: the old translations described controls that don't exist: a selectable cross-section model and a Wulff/Schmidt/hemisphere projection. They also said the energy histogram shows energy loss ΔE. English says it shows the energy the BSE still carries at escape, "not their energy loss".
• 9. HRTEM/STEM overview and 9.1 HRTEM: now use the current page structure. The old version put every setting on one page.

Content carried over from English

• Appendix A1.2: the section on the two definitions of the excitation error $S_g$.
• Macro reference: the ExcitationError row.
• Rotation geometry: the paragraph on intrinsic vs laboratory-frame Euler angles.
• EBSD: the Contrast slider, Flatten background and Match to image.
• Spot ID v2: the Global fit and Donut items.
• Physics corrections from 346be81:
  • A3 HRTEM: ΔE and Δ₀ are standard deviations, and the TCC limits are corrected.
  • F-lattice diagram note: "upper-left quarter of the projected cell".
  • CBED: the aperture is the probe-forming (condenser) aperture.
  • Attenuation: α_c with its validity caveats, and Jablonski (2008) for the stopping power.
  • Fluorescence: selection rules and the nuclear-charge explanation.
  • Scattering factor: the KLI wording.
  • Structure viewer: the tab introductions.
  • Main window: Peng 1996/1998, the zone-axis text and the F1 language note.
  • Troubleshooting: OpenGL 1.3 minimum / 4.3 recommended.
• zh-Hans and zh-Hant: fixed a corrupted $s \approx 3$ in the scattering-factor appendix, where a BEL control character had replaced \a.

GUI labels follow each language's .resx strings. Where a control has no localized string, the English UI label is used. Screenshots point to cap-<lang>-auto only where that file exists.

Verification

• A structural audit compared every translated page with English: headings, images, links, $$ blocks, inline math, tables and list items. No structural gaps remain. A few pages still differ by one in the inline-math count. That comes from wording only, e.g. $\det = 1$ written as one span, and the formulas are the same.
• mkdocs build -f docs/mkdocs.yml --strict passes with no warnings.
• No control characters remain in docs/src/**/*.md.
• Only files under docs/src/<lang>/ changed: 14 commits, one per language per pass.

Not changed (English source; possible follow-ups)

• The HRTEM/STEM pages use the heading "Waves", but the GUI group box is labelled "Diffracted waves".
• Some localized screenshots are older than the current UI. For example, the zh-Hans EBSD experimental-image tab has no Contrast, Flatten or Match controls.
• Some older translated pages still use English GUI labels throughout. Where this PR edited lines on those pages, it used the localized labels, so a few pages now mix the two.

Correction: an earlier version of this description said the STEM-EDX section of 2-stem-simulation.md documented a gated-out feature. That was wrong. 7f2ca45 gated STEM-EDX only temporarily, and 4.946 (034c5b0, 2026-08-05) released it, so the STEM-EDX documentation is current and stays.

Correct the Italian absorptive-factor equation

For readers using the Italian dynamical-diffraction appendix, this new paragraph defines $s_-$ and $s_+$ using $\mathbf K-\mathbf k_{vac}$, but the displayed equation immediately above still defines them from $\mathbf K$ alone. Those expressions are not equivalent when $\mathbf K$ is the scattered wave vector, so the page gives two conflicting integrands; update the displayed equation to include the current $\mathbf q=\mathbf K-\mathbf k_{vac}+(\mathbf g+\mathbf h)/2$ definition, as in the English source.
