fix: silence analytics 403 toast and update footer

- analytics/track: return 200 instead of 403 when disabled or bot
  detected — prevents the global API error handler from firing an
  "Unknown Error" toast on every dashboard page load
- Footer: replace ES flag with EU flag (12-star SVG polygon), remove
  paste.es link wrapper, hardcode tagline in Spanish, replace sponsor
  text with "Servicio ofrecido por Cloud Host"
