OverlayPassphraseSession

@Singleton

class OverlayPassphraseSession @Inject constructor

Caches decrypted passphrases per key id with a TTL and a hard capacity so the overlay can decrypt repeatedly without re-prompting, while limiting exposure.

Entries expire after a fixed TTL and the oldest is evicted past the capacity limit. All stored buffers are zeroed on removal.
