Removed menu items from my app. Less is more, sometimes #overmind

Merged the open positions and the AI portfolio dialogs. I think I want to eventually have everything in a single screen; it's easier for the user to just have one screen to check and execute everything.

Implemented a search bar, so I can filter what markets I want to manage more easily. Also added a button for training a single predictive model, instead of the whole portfolio (~50 markets. It was taking too long, even for 1 epoch).

Simplified the UI/UX of my app, embracing the KISS principle. Also, I just read a post by @rufuspollock , and I realized I lost my streak, but I also worked yesterday, haha

I refactored a huge, badly coded widget (Flutter) for showing the settings for training prediction models. I'm attaching a screenshot. It's ugly, but making it pretty should be one of the last steps before releasing :)

Integrated Stripe payments for monthly subscriptions. After a successful transaction, an API key is sent to the customer's email so they can start using my service. Woohoo!
