fix(frontend): Contact spre romfast.ro/contact; logo unic link spre home

- Linkurile Contact (footer landing + pagini legale, referința din
  Termeni) duc acum la https://romfast.ro/contact; pagina internă
  /contact și ruta ei au fost eliminate
- Pe paginile legale doar sigla e link către homepage; titlul
  „ROA Space" nu mai e link
