docs: clarify Argon2id and BLAKE2b-512 KDF usage

Browse Source 
Document BLAKE2b-512 and Argon2id usage in the HTML/CHM user guide and Russian/Chinese translations. Clarify Argon2id's non-system scope, PBKDF2-HMAC system encryption behavior, PIM parameters, and regenerate the CHM files.

In the Volume Creation Wizard, in the password change dialog window, and in the Keyfile Generator dialog window, you can select a hash algorithm when using PBKDF2-HMAC as the key derivation function. When Argon2id is selected as the key derivation function, no hash algorithm selection is available as Argon2id uses its own internal BLAKE2b hash function.
In the Volume Creation Wizard and in the password change dialog window, you can select a hash algorithm when using PBKDF2-HMAC as the key derivation function. In the Keyfile Generator dialog window, the selected hash algorithm is used by the VeraCrypt Random Number Generator as its pool mixing function. When Argon2id is selected as the key derivation function, no separate hash algorithm selection is available for header key derivation because Argon2id uses its own internal BLAKE2b-512 hash function.

For PBKDF2-HMAC, the user-selected hash algorithm is used by the VeraCrypt Random Number Generator as a pseudorandom &quot;mixing&quot; function, and by the header key derivation function (HMAC based on a hash function, as specified in PKCS #5 v2.0) as a pseudorandom function. When creating a new volume, the Random Number Generator generates the master key, secondary key (XTS mode), and salt. For more
