Feat/stacks signer block proposal

[jferrant]

Description

This is a rather large PR...please forgive.

major changes include:

• Complete reorg of the stacker db and stacks clients
• Complete reorg of the signer integration tests for easier adding of tests
• Changing libsigner to take SignerEvents rather than StackerDBEvents as we now need to subscribe to blocks
• Handling the new block proposal events within Stacks signer
• Added a test to handle a validated block (against the RPC endpoint)
• Enabled stackerdb_dkg_sign test as well since I made substantial changes to the test layout to ensure it still works

Applicable issues

• Closes Nokamoto[Block Proposal]: Signer binary handles BlockProposal event stored to StackerDB #3928
• Closes Nakamoto[Block Proposal]: Signer binary submits block proposal to stacks-node for validation #3929

Additional info (benefits, drawbacks, caveats)

Major items left to do that are NOT included in this PR

• State needs to be added to the signers to allow them to filter out already seen blocks requests/block validation responses/block sign requests. See [Nakamoto] stacks-signer needs track processed blocks responses, block requests, and block sign requests #4242
• Block is not properly deserialized during signing rounds to enable verification of a sign requests contents. See Nokamoto[Block Proposal]: Signer binary issues signature and broadcasts the block #3930
• State needs to be added to verify a block contains the expected transactions [Nakamoto] stacks-signer needs to track its transactions to verify a block contains these special cased transactions #4243

Checklist

• Test coverage for new or modified code paths
• Changelog is updated
• Required documentation changes (e.g., docs/rpc/openapi.yaml and rpc-endpoints.md for v2 endpoints, event-dispatcher.md for new events)
• New clarity functions have corresponding PR in clarity-benchmarking repo
• New integration test(s) added to bitcoin-tests.yml

This looks great to me, just had a few comments

[kantai]

LGTM!

[jcnelson]

Isn't this stackslib:: now, instead of blockstack_lib?

[jferrant]

I don't find it that way. as far as I am aware its still blockstack_lib. Can find no instance of stackslib::* throughout the code base.

Just a couple comments. Thanks!
