WIP

I added (at least I think so) bitcoin chain tip and mapping bitcoin height => first stacks block ancored to this bitcoin block height to db. Also, wrote a function which returns total withdrawn amount using this info.

TODO:

• add everything needed to keep this new tables in db up to date
• add endpoints to provide results of this function to external consumers
• fix various bugs and style issues
• add tests
• fix some .env files and other things to make this new tables in db work

Oookay, now it should be mostly done. There are a lot of small things to fix, but core changes and logic are done I think

Or maybe @matteojug you have more bandwidth for reviews =)

note: I'm not asking for full review, it is still WIP, just approve that logic is generally ok and I can do some cleanup
