Fix deploys from main - remove migration file for now

[otherview]

Why this change is needed

Fixes deploying testnet/dev-testnet/sepolia from main.
This PR bypasses the use of migration and avoids triggering the bug in the migration code path.
The reason why the migration code is breaking is still to be determined, but likely a string format thing ?

Currently when adding a 002_init.sql file the enclave fails to start with the following error:

CRIT [09-20|17:25:22.278] Failed to connect to backing database    node_id=0xc272459070A881BfA28aB3E810f9b19E4F468531 component=enclave      
err="unable to execute migration for 001_init.sql - Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'CREATE DATABASE obsdb;

I don't understand the reason for the changes in this file? Since the 002 file was removed

It clears up comments and a variable name that threw me off the first time I was reading the code, and adds more info to the error.

Made those changes while debugging the code initially, and felt like they would be good to keep.
Likely it would be good to keep the comment and the error, but perhaps change back the var name if you prefer ?
What do you think ?
