[PM-23280] Use masterPasswordUnlock KDF settings on vault unlock

[andrebispo5]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-23280

📔 Objective

KDF Conversion Improvements

• Added a new extension function KdfJson.toKdf() in KdfExtensions.kt to convert a KdfJson object to a domain Kdf type, applying default values for Argon2 parameters when not provided.

Vault Unlock Logic Update

• Updated the AuthRepositoryImpl vault unlock flow to use the masterPasswordUnlock kdf parameters when they exist, or fallback to the account.profile kdf otherwise. This ensures the vault is unlocked with the correct KDF settings.

⏰ Reminders before review
