[ADD] Estate Account Module & Correction

Added the new module estate_account and I fixed most of the suggestion from previous comments

1. Problem: None
2. Objective:
- Finish the tutorial 101. Sometimes go a bit beyond (ex: smart button with invoice)
- Make the necessary adjustement to have a nice code for the next code review.

3. Solution: Code and follow tutorial :)
