i18n: add translations for new v2.7 UI strings across 14 languages

Fills previously missing msgstr entries in fr, es, it, nl, pl, ru, uk,
tr, pt_BR, sv, cs, hu, ko, ja covering the same string categories
already translated for de in a prior commit:

- Texture import workflow (Multi-Color, Color Count, Filament Mapping,
  Skip Matching, Computing/Applying texture colors, Texture Import
  Warning, Auto-merge same filament, etc.)
- Device status / pause messages (filament ran out, nozzle clog/clumping,
  step loss, AMS offline, heatbed/nozzle temperature malfunction,
  chamber control problem, Gcode by user, front cover, heatbreak fan)
- Calibration states (flow ratio, dynamic flow, BirdsEye Camera,
  Live View Camera, motion accuracy)
- General UI labels (Filter, Saving, Limits, Cool, Fast, Text,
  Software Update, Current Version, Filament Manager, Nothing selected,
  Purge Mode Fast/Standard, Printer/Process/Filament presets, etc.)
- Beta update flow (New Beta Available, Don't show again, Why use Beta,
  Try Now, Importing model, Updating 3D view, Model imported)
