Pull request overview
Adds DHUK-based wrapping/unwrapping for the token seed when persisting it to storage (STM32U5), so the seed used for deriving the token key is not stored in plaintext.
Changes:
- Introduced DHUK AES-CBC wrapping format for the stored token seed (length + IV + ciphertext).
- Routed token load/store seed read/write through new DHUK-aware helpers when
WOLFSSL_STM32U5_DHUKis enabled. - Minor clarifying comment in user login path about re-deriving the token key from PIN + seed.
