Fix float and uint64_t comparison (#23199)

fix: ControlAllocator float and int comparison bug

There was an incorrect comparison between a float variable `dt` and a `uint64_t` value representing 5 milliseconds (`5_ms`). As a result, `do_update` could never become true even if the last torque setpoint was received more than 5 milliseconds before.

To solve this, the `5_ms` value has been converted to seconds (0.005f) for the comparison with `dt`.
