Swedish adaptation: Instegscertifikat and HAREC

- Editions replaced by INSTEG, HAREC and UPPGRADERING (Instegscertifikat -> HAREC)
- Question pool optional; simulator, homework tool and solutions switch off without one
- All UI strings, templates, renderers and project JS localised to sv-SE
  (decimal comma, Swedish non-breaking-space rules, Å/Ä/Ö in Morse table)
- DARC branding, membership CTA and German links removed; attribution footer added
- Page names centralised in src/pages.py
- README and docs rewritten in Swedish
