Recurring charges windows

This is a follow-up ticket for https://moneymatter.featurebase.app/p/sort-bills-and-subscriptions-by-due-date. Would be nice to support custom “windows” for recurring charges, so users will be able to keep track of “what’s coming in the next exact window” – useful for weekly/bi-weekly lifestyles. The expected functionality:

1. Being able to “filter”/show only the charges in the specified window

2. Being able to move between windows backward/forward

3. Being able to see a “summary” for the selected window – the expected charges amount
