fix(zerion-uniswap-x402): use canonical 5-arg zerion bridge signature (#75)

The bridge signature regressed to the 3-arg form, but the CLI only accepts
the 5-arg form `<from-chain> <from-token> <amount> <to-chain> <to-token>`.
Path A agentic runs hit missing_args and stop. Aligns with the form already
used in zerion-uniswap-lp. Also adds missing trailing newline.
