Since the very first 0.1.0-alpha.1 release, we've been moving quickly to add new features to the Maybe app. In doing so, some parts of the codebase have become outdated, unnecessary, or overly-complex as a natural result of this feature prioritization. Now that "core" Maybe is complete, we're moving into a second phase of development where we'll be working hard to improve the accuracy of existing features and build additional features on top of "core". This PR is a quick overhaul of the existing codebase aimed to: - Establish the brand new and simplified dashboard view (pictured above) - Establish and move towards the conventions introduced in Cursor rules and project design overview #1788 - Consolidate layouts and improve the performance of layout queries - Organize the core models of the Maybe domain (i.e. Account::Entry, Account::Transaction, etc.) and break out specific traits of each model into dedicated concerns for better readability - Remove stale / dead code from codebase - Remove overly complex code paths in favor of simpler ones
