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

* Smalbandigt filter
* Undertrycker en bestämd LF-frekvens
* Kan realiseras i LF- eller FI-delen

<note>
* Störendes Signal, z.B. Träger ausblenden
* Im ZF-Bereich können stärkere Störsignale wirksamer unterdrückt werden
* Hat dann weniger Einfluss auf die AGC
* Notch-Filter sind im Funkgerät oft anpassbar (Frequenz, Bandbreite, Filtercharakteristik)
* Auch als Auto-Notch-Filter möglich
* Tar bort en störande signal, t.ex. en bärvåg
* I FI-delen kan starkare störsignaler undertryckas effektivare
* Påverkar då AGC mindre
* Notchfilter kan ofta justeras i radion (frekvens, bandbredd, filterkarakteristik)
* Finns också som auto-notchfilter
