Put new and stale sections side by side

[ftomassetti]

• date column should show just the date
• we probably do not need the state column for the new patchs
• put new and stale side by side

@lu-zero thoughts?

Reference:
@kodabb

graficamente preferirei meno spazio orizzontale abusato: righe meno
alte e la sezione "stale" e "new a pari livello, disposti
orizontalmente

It would need to have less columns and surely can be done.
