Allow reading the progress data from the custom tables

[m1r0]

Goal

Currently, the progress repository is fetching the data from comments. The goal of this card is to start reading data from the tables once the data migration is done.

Scope

• Enable the progress repository classes to read the data from the custom tables instead of the comments.
• Create new cards if there are bugs.

I was thinking about how to process two flags: use tables (feature enabled) and read from tables (the new one).

I realized that adding that reading from tables (and writing to comments) logic to the existing aggregate repository will make that repository too intricate.

The more straightforward solution is to add a new aggregate with all that logic.

The factory, looking at flags, decides which aggregate to create.
