Subject: [PATCH] feat(auth): toggle mostra/nascondi password sul login admin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Il campo password non offriva modo di rileggere quanto digitato, quindi
un accesso fallito era indistinguibile da un errore di battitura.

Toggle inline e non nuovo primitivo in ui/: `type="password"` compare una
sola volta in tutto il codebase. type="button" perché dentro un <form> il
default è submit, e tabIndex -1 per tenere il Tab sulla sequenza campo →
Accedi. Classi a token semantici; gli hex literal preesistenti di questa
pagina restano da migrare a parte.
