fix: use top-level import type in checkpoint-proving-state

Removing the value constants (NUM_BASE_PARITY_PER_ROOT_PARITY, NUM_MSGS_PER_BASE_PARITY)
left an @aztec/constants import whose members are all inline-type, which
@typescript-eslint/no-import-type-side-effects rejects. Convert to import type.
