feat(ui): dashboard ribilanciata + trial banner d'impatto + masthead minimale

Tre fix di vestizione dopo il primo "sguardo dal vivo" della dashboard loggata:

1. **Masthead minimale**: rimosse "ANNO I · N. 01" e data corrente che davano un sapore "magazine vintage" stridente con la nuova typography Geist. Ora solo logo a sx + (opzionale) etichetta sezione a dx, divider sottile.

2. **TrialBanner d'impatto**: era un avviso sussurrato (bordo dashed oro su crema). Adesso card scura full-width con mesh-blob oro animato, numero giorni in mega 4xl/5xl con accento oro, CTA bottone solido oro→pomodoro al hover. Diventa il primo focus visivo della dashboard, coerente col fatto che è la conversion principale.

3. **Dashboard bilanciata**: hero "Piano della settimana" allargata da `md:col-span-6` a `md:col-span-7` + rotazione ridotta da `-rotate-1` a `-rotate-[0.5deg]` (meno dramma). La nav resta su 5 col da col-start-8, ma con un `pl-2` chiude lo spazio fra hero e prima voce, eliminando il "buco" centrale di aria. Rimossi anche chapter marker gigante "I" e vertical text "Continua la lettura" che rinforzavano il sapore magazine.
