Bitcoin wallet: Docker-based integration tests (bitcoind + electrs)

[nopbody]

Closes #799

added proper end-to-end integration tests for the bitcoin-wallet crate by running real Bitcoin services inside Docker instead of mocks. It spins up a regtest bitcoind with electrs and verifies core wallet flows like receiving, sending, broadcasting, and confirming transactions. This helps catch real-world issues early and makes the wallet logic much more reliable.

@binarybaron Follow-ups / WHICH cases to add next (tracking list)?

[nopbody]

@binarybaron, this approach matches the repo’s existing integration test patterns, All tests pass reliably on clean Docker setups; failures are clear if Docker isn’t running.
Do you have anything particular/specific about this that feels off? - any edge cases or style tweaks you spot?
let me know.
thanks

Will review soon. Is the PR description AI generated ?

used AI just to refine the wording, but the implementation and reasoning are mine.
Happy to explain any design decision or can walk you through any part if needed.

Not really. We will review this when we find the time. Thank you though.

Can you re-write the description yourself or delete it entirely? If I want a AI summary I can run Claude Code myself.

Done

I'll mark as ready for review in order to run the tests in CI.

just a heads up that, still need to decide and implement WHICH cases to add next.
