[PM-26585] Remove InitUserCryptoMethod::Password in favour of InitUserCryptoMethod::MasterPasswordUnlock

[mzieniukbw]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-26585

📔 Objective

Remove SDK’s InitUserCryptoMethod::Password.
Remove InternalClient’s function initialize_user_crypto_master_key, rename to initialize_user_crypto_key_connector_key.

Moved existing usages (mostly testing) to InitUserCryptoMethod::MasterPasswordUnlock or initialize_user_crypto_master_password_unlock.

🚨 Breaking Changes

None expected.
Mobile already migrated off InitUserCryptoMethod::Password.
Client's WASM uses InitUserCryptoMethod::DecryptedKey (just so it can pass decrypted user key)
