Change ft merge

This PR:

• updates how data is merged into the pg db for EVM.
• updates the imported code from liquidity layer.
• uses a different approach to look for fast transfers on EVM.
• picks up a newer version of the example-liquidity-layer repo in the submodule.

confirmed I was able to reproduce the .tgz artifacts with the following commands

cd watcher/sdk/example-liquidity-layer/evm 
make
cd -
cd watcher/sdk/example-liquidity-layer 
npm ci
npm run build
npm run pack
cp *.tgz .. 
cd -

would be good to have the makefile do this and best to have CI confirm it a la https://github.com/wormhole-foundation/wormhole/blob/main/.github/workflows/build.yml#L262-L263

just gave a high-level pass. could be a couple things worth cleaning up, but could be merged as is given that it's independent.
