Swedish adaptation: Instegscertifikat and HAREC content

Browse Source 
- Sections and slides rewritten in Swedish; German law and institutions replaced by
  Swedish/CEPT/ITU equivalents (PTS, SSA, PTSFS 2025:1, SSMFS 2008:18), unverified
  statements marked "% TODO VERIFY"
- New toc: INSTEG, HAREC, UPPGRADERING; section idents are Swedish (see ident-map.tsv)
- Exam-question tags, BNetzA question pool, solutions and the German SWL course removed
- Static pages, snippets, applets, READMEs and image alt-texts translated
- TikZ labels translated; SVG drawings regenerated (drawing 689 still fails to build
  upstream: it references a missing photo)
- Changed from the original: not endorsed by DARC e.V., SSA or PTS

Bandbredden hos en signal eller utsändning mäts i hertz ($\unit{\hertz}$). Man mäter signalens bandbredd som skillnaden mellan utsändningens högsta och lägsta sändfrekvens.

Bandbredden anger alltså hur mycket spektrum signalen tar i anspråk. Vanligtvis mäter vi bandbredden hos en signal mellan de frekvenspunkter där den spektrala effekten har sjunkit till $\frac{1}{2}$ (motsvarande $\qty{-3}{\dB}$) av topvärdet.
