Fix daily quest progress tracking

[AminArria]

Motivation

Closes #926

Summary of changes

• Change to preload all quests for the week
• Filter out quests from not today when calculating progress

How to test it?

The following steps assume you are starting from clean DB (mix ecto.reset)

1. Create a new user (easier to login with Unity)
2. Run the following SQL to move the daily quests to yesterday

update users set last_daily_quest_generation_at = '2024-09-12 17:00:00';

update user_quests set activated_at = '2024-09-12 17:00:00', inserted_at= '2024-09-12 17:00:00', updated_at= '2024-09-12 17:00:00';

-- The line below could potentially mark the milestone quest as completed, but regardless I don't think its an issue
update user_quests set status = (case when random() < 0.5 then 'completed' else 'available' end) ;

3. Login again through Unity to create todays quests

Now if you go to the quests tab you will see yesterday completed progress. Try to complete some from today to make sure everything still works as expected

This was the main culprit for the 0/6 error, it was preventing the fetching of previous day quests so as a result it was always showing as 0
