Add WebStore to miden-client

[dagarcia7]

Summary

This PR adds the WebStore, a WASM-compatible implementation of the miden-client Store trait.

It uses IndexedDB as its backend storage method to provide dependable, high-performance, and persistent storage for web-based clients, enabling seamless interaction with the Miden node in web contexts.

The existing SqliteStore utilizes SQLite as its backend, taking advantage of its robust and efficient database capabilities for data persistence. SQLite is a widely-used, serverless, self-contained SQL database engine that offers stable storage and effective querying for applications.

However, SQLite is not compatible with WASM due to its reliance on native file system access and multi-threading, which are not available in the web environment. WASM operates within a restricted sandbox in the browser, lacking direct access to the underlying file system and threading capabilities that SQLite requires.

Addressed as much feedback as I could! Just a heads up, I'm seeing this when I run cargo build --features idxdb

I think this also shows up in regular, non WebStore builds too. Is this a known error?

Running cargo update may fix this.

Fixed!

Seeing this now in the integration tests

Unsure what that could be as well!

You probably need to rebase this branch from the latest next (if I'm reading the error correctly, it is trying to get miden-node code from a branch which has been merged into next already).

I should be rebased I think 🤔 I tried to do this locally, but not sure if it's the same conditions given that I'm on a forked repo and there's funkiness with origin vs. upstream

@dagarcia7 #407 got merged, it'll probably get some conflicts when you merge/rebase
