fix(authwit): update split-time consumer imports

- schnorr/simulated_schnorr account contracts and uniswap_contract still imported authwit::common::*; rename the path to authwit::utils::* to match the split.
- app_subscription_contract: revert the spurious 'use public_checks::utils::privately_check_block_number' (the public_checks crate is no longer a separate crate after #23215 moved the helpers into aztec-nr) back to 'use aztec::public_checks::privately_check_block_number'.
