Lumy for YNAB 4+

Additions:

- Design updates across the application to simplify the design system and make it simpler to introduce new UI
- Added the ability to sort the Recurring Transaction (by Payee) report alphabetically and by amount in both ascending and descending fashion.
- Report periods are now "trailing", meaning if you select, for example, the Latest 3 Months Period in December, you will initially see reporting for October, November, and December. However, on Jan 1, you will start seeing reporting for November, December, and January without needing to re-select Latest 3 Months like you would've had to do prior to this change. This was one of the primary changes as a result of [this ticket](https://lumyforynab.canny.io/features-and-bugs/p/timeframe-chooser-improvements).
- The Frugal Month Section on the Budget Tab now highlights the Left to Spend amount instead of the status. The status can be seen by tapping the Frugal Month tile. Additionally, when a Frugal Month is active, it shows above the Spent this Month section.

Fixes:

- Fixed an issue with the Advanced Spend Tracker Query Builder for Advanced AST users where having enough conditions would make it impossible to add more.
- Fixes the Send Feedback form so you can actually send feedback via the app now...We were wondering why it'd gotten so quiet!

Removals:

- I have decided to remove the (barely in beta) Goals feature. It may be revisited at a later time, but the amount of work it would take to maintain the feature as initially scoped would be way too high for a one-man team. For now, I'd like to focus most of my efforts on functionality I feel is more at the heart of what Lumy aims to do, such as more advanced reporting functionality.
- Additionally, the "Highlights Section" has been removed from the Budget Tab for a couple reasons. The Left to Spend metric was redundant with the Burndown section title and now that the Frugal Month section shows the current Left to Spend amount, it was no longer needed. The Days of Buffer metric was confusing more folks than it was helping as it didn't align with the DOB metric shown on the Reports tab due to them using potentially different look-back periods (for reasons explained in Discord but not worth rehashing here). If you want your DOB number, check out the report on the Reports tab. For the most part, this number shouldn't change often or have huge swings, so having it front and center on app-launch seems a bit unnecessary. Lastly, the Overspent and Over-budgeted metrics were removed as well due to the fact that there is nothing you can do within Lumy (at this point) to take action on those, so they weren't really helpful.
