Rewrite /admin/pipeline/[id] LeadDetail with token-based dual-theme layout:
bespoke header with inline StatusBadge, asymmetric 1/3 profile + 2/3 content
columns, and a unified reverse-chronological timeline merging activities and
transcripts (transcript node highlighted + expandable + deletable).
Restyle modal triggers (Registra Attività, Aggiungi Transcript, Modifica-as-icon)
to the mock outline style. Remove the confusing "Invia Preventivo" button (it only
linked a token + advanced stage, no email). Keep Converti in cliente for won leads.
