fix(wallet): widen bank_card_number columns and cap input length

Module 3 step 1 (output application) had no length limit on the bank
card number fields in either the frontend input or the backend DTO.
A long test value overflowed VARCHAR(30) and the MySQL update failed
with 'Data truncation: Data too long for column bank_card_number',
returning a 500 and blocking the whole module 3 flow (and therefore
module 4/5 downstream).

- widen wallet_application.bank_card_number/input_bank_card_number,
  bank_received_wallet_application.bank_card_number,
  wallet_registration_request.bank_card_number, and
  central_wallet_registration.bank_card_number from VARCHAR(30) to
  VARCHAR(64) in schema.sql (already applied directly to the running
  dev database via ALTER TABLE)
- add @Size(max = 64) to WalletApplicationRequest's card number fields
- add maxlength=64 to the bank card input on the wallet open step
