feat(cat-voices): vault crypto

[damian-molinski]

Description

Adds encryption of all data coming in/out of Vault using VaultCryptoService.

Key derivation

Pbkdf2 key derivation algorithm instead of Argon2id because BrowserCryptography has native browser implementation of it and times are significantly faster (0:00:00.001200 instead of 1.3s!).

Encryption / Decryption

AesGcm with 256 bits is used.
