refactor: library api reorganization

[mFragaBA]

closes #362.
closes #284.

I tried to have each commit as self contained as possible:

• b84c845 refactors the re-exports for the library crate to have a more flattened structure (the code structure stays as is, only exports change)
• 9251fb1 makes StoreConfig an associated type of Store. This allows the consumers of the library to re-use the ClientConfig struct when providing their own store implementation. Not only that but we expect it to satisfy a few trait bounds (usually they can be derived) such as Debug, Default, Eq, PartialEq, Serialize, DeserializeOwned.
• 9587e23 and dde95bb adds features to enable the sqlite store and the tonic rpc client respectively
• 5eebbc5 is pretty self descriptive. The reasoning is that concurrent implies std in base so we should add it here as well to be explicit about it.
• 503a1c9 we remove the feature flags uuid and test_utils. This comes at a bit of a cost. Unless we're on unit tests of the client, we can't use anything under #[cfg(test)] because in those cases (like the CLI and integration tests) the client gets compiled but not in test mode. I couldn't find a built in way to do so and the workaround is what we had with test_utils which is to define a custom feature flag, but the problem is that it cannot be hidden. In order to remove uuid and test_utils I also had to remove some tests from src/cli/..., but considering we're adding very similar tests on feat: add CLI integration tests using assert_cmd #353 it's not a big deal.
• In f87000b we wanted to stop exporting CliConfig from miden_client. The way to do so was by inverting the dependency between it and the ClientConfig struct. So we go from "A ClientConfig can have a CliConfig defined" to "All CliConfig has a ClientConfig defined"
• Lastly, in ff56c79 was something mentioned in comments where we could stop exporting rusqlite and rusqlite_migration as features by prepending them with a dep: on Cargo.toml

Discussion

• I'm thinking that in order to split dependencies that are CLI only we'll probably need to change this into a workspace and have a separate crate for the CLI. That way we can, for example only require figment for the CLI. I think that's a second refactor we could leave for a separate PR, but we can tackle it here.

The changes in miden_tx broke some of the imports here, I already commited some fixes to the parent branch so we only have to merge them.

done! Rebased and pushed

Looks good! Thank you! I left some comments inline. Also, a few comments about the errors module:

• IdPrefixFetchError seems like CLI-specific error. I think we should remove it from the public library interface.
• InvalidNoteInputsError seems like an internal-only error which doesn't appear in the public interface. If so, we should hide it (e.g., use pub(crate)).
• Should we rename NodeRpcClientError into just RpcError? I think having words Node and Client there is making things more confusing.
• We should probably rename ScreenerError into NoteScreenerError.

In general, I'm wondering if we need this module at all or maybe we should just move (or just re-export) error types into relevant modules (e.g., RPC error would be in the rpc module).

• InvalidNoteInputsError seems like an internal-only error which doesn't appear in the public interface. If so, we should hide it (e.g., use pub(crate)).

While it does not appear in the public interface directly, it is used in NoteScreenerError which is part of the public api. Making InvalidNoteInputsError results in the following warning:

Ah - I see! Let's keep it as is then.

Looks good! Thank you! I left a few more comments/questions inline (in addition to the ones above). But overall, I think this is good to be merged.

Looks good! Thank you! I left one small comment regarding the config file - but other than that, I think this PR can be merged.
