Fix constants to enable indexing of new pairs and pools

[gianfra-t]

After the addition of new swap pairs for Amplitude and Pendulum, we need to make some changes to the hard-coded constants in the processor required to properly index the events.

For instance, here we need to add all the relevant tokens that are used in the pairs on both chains.

We also need to ensure that relevant types (farming, zenlink) are generated for Pendulum.

Finally, we need to modify the use of the hard-coded CHAIN_ID constant currently pointing to Amplitude.

Hey team! Please add your planning poker estimate with Zenhub @b-yap @bogdanS98 @ebma @gianfra-t @TorstenStueber

Very urgent as blocking the Zenlink pools on Amplitude, moved to ready without it being estimated.

I pushed a "hotfix" to our squids and now we can see the new pools. But still this needs to be worked and cleaned.
