Replace the raster logo with the original vector, drop the webshop line

The logo was blurry because logo.png came from a 320x60 JPEG. It is
drawn 299 css px wide, so a 2x display needs ~597px and a 3x phone
~896px - it had roughly half, respectively a third, of the pixels it
needed. No amount of rescaling fixes that.

The real source was in the repo's own history instead: the prototype
in Downloads/lara-webdesign.html carries the mark as one SVG with a
single viewBox - the wave field plus the "larpaso" wordmark as a path
drawn from EB Garamond italic. Both paths, the sage/straw/rose gradient
and the petrol #2C4A42 are taken from there verbatim, so this is the
decided mark, not a redrawing. It only looked like a smooth pill
because the JPEG was too coarse to show the waves.

The "WEBDESIGN" label is converted to outlines from Schibsted Grotesk
rather than set as <text>: an SVG loaded via <img> gets no webfonts and
would silently fall back to a system face - the same reasoning the
existing wortmarke-zu-pfad.py gives for the wordmark.

Also removed "Keine Onlineshops." from the "Was wir nicht machen" list,
as requested. The price list still reads "Nicht enthalten: Fotoshooting,
Logo-Neuentwurf, Onlineshop" - that one scopes the 500 € package rather
than declaring what we do at all, so it is left for now.

logo.png and logo.jpg stay in place as fallbacks.
