Add missing cards.learnMore key to Italian UI strings

[Copilot]

Italian (it.yaml) was missing the cards.learnMore key present in English and all other locales, causing a fallback to the English "learn more" text on pattern cards.

Change

Added the missing key to translations/strings/it.yaml:

cards:
  ...
  touchHint: 👆 tocca o scorri →
  learnMore: scopri di più   # ← added

Italian now has full parity with the English string set (91 keys).
