Increase MaxInputSize to 16MB in op-alt-da

On `celo10` branch I've observed in the batcher:

```
{"t":"2024-10-17T15:24:33.473665645Z","lvl":"crit","msg":"Application failed","message":"failed to setup: failed to init channel config: max frame size 999999 exceeds altDA max input size 130672"}
```

With previous `celo` versions this size limit was not enforced, and we increased the max frame size to 16MB in the derivation pipeline ([PR](#228)).
