Merge main v1.46.6 into feat/ru-locale

- baselines: take main's entries, keep the two ru-driven line counts (coach-prose-grounding 1091, insight-generator 1115) and regenerate the function baseline.
- messages/ru.json: translate the five unit-less markers keys the release added (labs.unit.none/noneHint, labs.ocr.errorUnitMismatchNoUnit, labs.ocr.unitDiffersBadgeNoUnit, recordImport.unitlessHint) — parity is 11 159 keys again.

+"""Build the fonts the doctor-report PDF embeds.
+
+jsPDF draws one font per text run and has no glyph fallback, so every script
+the report can carry has to live in one font file. No single upstream Noto
+font covers what the report needs: Noto Sans has Latin, Greek and Cyrillic but
+no arrows or comparison signs, Noto Sans KR has Hangul but no Latin
+Extended-A (Polish). This script merges them:
+
+  ReportSans-{Regular,Bold,Italic}.ttf
+      Noto Sans (Latin, Latin Extended-A/B, Greek, Cyrillic, punctuation,
+      super-/subscripts, currency) plus the arrows and mathematical operators
+      of Noto Sans Math.
+  ReportSansKR-{Regular,Bold}.ttf
+      The matching ReportSans weight plus Hangul (syllables, jamo,
+      compatibility jamo) and CJK punctuation from Noto Sans KR, instanced
+      at weight 400 / 700. Loaded only for a report that contains Hangul.
+
+All sources are SIL Open Font License 1.1; the licence texts sit beside the
+output. The merged fonts carry their own family name, as the OFL asks of a
+modified version. Layout tables (GSUB/GPOS/GDEF/MATH) are dropped: jsPDF
+does no shaping, and precomposed Hangul syllables need none.
+
+Requires fonttools (`pip install fonttools`). Usage:
+
+  python3 scripts/build-pdf-fonts.py <download-dir> <output-dir>
+
+where <download-dir> holds the unhinted upstream TTFs:
+  NotoSans-Regular.ttf, NotoSans-Bold.ttf, NotoSans-Italic.ttf
+    https://github.com/notofonts/notofonts.github.io/tree/main/fonts/NotoSans/unhinted/ttf
+  NotoSansMath-Regular.ttf
