Smittix bcf447fe4e fix: prevent root-owned data files from breaking radiosonde start ...

Running via sudo creates data/radiosonde/ as root. On next run the
config write fails with an unhandled OSError, Flask returns an HTML 500,
and the frontend shows a cryptic JSON parse error.

Three-layer fix:
- start.sh: pre-create known data dirs before chown, add certs/ to the
  list, export INTERCEPT_SUDO_UID/GID for runtime use
- generate_station_cfg: catch OSError with actionable message, chown
  newly created files to the real user via _fix_data_ownership()
- start_radiosonde: wrap config generation in try/except so it returns
  JSON instead of letting Flask emit an HTML error page
