13e6c4f55d fix(crypto): fix cash_encode 
- Fixed description of buffer sizes in the header file.
- Added check of hrp length in cash_encode. Otherwise it allows to encode addresses that cannot be decoded using cash_decode.
- Adjusted naming of constants and parameters for clarity and consistency.

9b1c06205c fix(crypto): Fix side-channel vulnerability in BIP-39 mnemonic processing 
Fix function `mnemonic_to_bits` to be constant time. Replace binary search over the wordlist with a linear search to ensure the same number of comparisons.
Introduce function `constant_time_memeq` that comapres two parts of memory in costant time.
Remove integrity check in legacy to reduce the number of computations over seed.

(cherry picked from commit 4e6f0dee81)
