Add rpc validation

[lucasbalieiro]

to be merged after #159
closes #161

This is adding a RPC auto-discovery that will try to probe the network, version and IBD state of the node.

For testing I've listed the edge cases that I found when working on this here: #161 (comment)

Also, I recommend testing from the dev mode and from the docker node.

Some prints of my test cases:

ready for review.

I checked that the current state of this PR is working on dev mode, as docker container and also worked on my Umbrel and it was able to identify the Node version, pre-fill the form for the node.sock validation

I tested this PR on my Linux, and I have a couple of points to discuss:

• the RPC discovery is not working on my end, and that's because of the following AI's explanation:

  host.docker.internal:host-gateway can exist on Linux, but it points at the Docker bridge gateway. If Bitcoin Core RPC is only listening on 127.0.0.1, the helper container won’t reach it through that bridge address. NetworkMode: 'host' makes the helper’s 127.0.0.1 be the host’s loopback on Linux.
  

• in case the RPC probing doesn't work, I would show the following text instead of the current one (which is a bit too much verbose IMO): We couldn’t automatically detect your Bitcoin Core node. If it’s still starting, wait a moment and retry. If it’s already running, you can continue and enter the connection details manually.

• in case the RPC probing works, we should immediately do the IPC probing as well, and only guide the user to the current "Bitcoin Core Connection" if that fails, otherwise that can be skipped entirely IMO

• if the RPC (or IPC) probing fails, it's correct to redirect the user to the "Bitcoin Core Connection" step, but currently the node's version (in case the RPC probing worked but the IPC failed) is being displayed as "Version: 300200" and not "Version: 30.2 • Synced":

@GitGab19, Text updated. version fixed.

About auto-advance, added in a new commit because I had to add new callback and do other validations ahead of time eee9850

Tested the feature on umbrel and mac and it is working

[GitGab19]

I just tested again, and on Linux it's not able to get the information through RPC.

To make it work on my Linux, both dev and docker deployments, I had to push this commit: GitGab19@26dd208

You can find it at https://github.com/GitGab19/sv2-ui/tree/pr-162 in case you want to cherry-pick it.

@GitGab19, cherry-picked 26dd208

Great, I tested everything and it's working on my end.
