chore(e2e): run the e2e dev server on native Linux

e2e.sh and gen_fixtures.py assumed WSL driving the Windows toolchain.
They now detect WSL (a microsoft kernel with cargo.exe available) and
otherwise use native tools:

- e2e.sh: cargo/curl instead of cargo.exe/curl.exe, pgrep/pkill
  instead of tasklist/taskkill, Linux paths in the generated .env, and
  binaries without the .exe suffix.
- gen_fixtures.py: picks the first ffmpeg that has the drawtext filter
  (a minimal build earlier on PATH may not; E2E_FFMPEG overrides), finds
  a monospace font with fc-match, and only translates paths with wslpath
  for .exe tools.
- Quote USER_NAME in the generated .env: the unquoted space made the
  dotenv parser reject the line.
- Mark the scripts executable.
