feat(budget): manage your daily expenses (N26 only)

[MadeInPierre]

Description

Hi all!

I recently discovered that there is an open Python API to access N26 accounts, so of course I had to make a daily expense manager based on it:

The idea is to ask a few questions about each expense :

• If you pay all/part of the expense for someone else, how much did you actually pay for yourself?
• Have they paid you back yet?
• Was this expense necessary? It could be fixed, variable, for hobbies, purely optional, for fun, ...
• etc.

Then, we could show simple statistics for each month (and cumulative yearly expenses) about how much you spent on each category/necessity.

Everything is stored on a Google Sheets on our personal account which acts as a database and is accessed through a Python API.
