Wallet enabling rework

[ghost]

Will close #1212 when ready.

It's in a draft stage for the moment.

You can start checking @smk762

i suggest:

• try with 5-10 coins enabled, logout/login multiple times
• same with 50~coins
• same with 100~coins

If you have any suggestion on the behaviour meanwhile coins are getting "enabled" please feel free.

One of my suggestion would be to split into more batches if more than 5 coins are enabled at the same time or on starting.

What do you think @tonymorony ?

This way if one coin cause the whole batch to not be answered we can have more batch

we can also do a batch less solution, and enable one by one

[smk762]

• batch all parent coins first
• batch the rest in groups of 5 or 10

Detected various frontend issues:

• Notifications panel UX not good
• Dashboard "Show only coins with balance" switch also affects the wallet page which should not be the case
• Improve dashboard's coins list loading time

I found the reason of the slowing bug when enabling lot of coins, it's due too:

src/core/atomicdex/models/qt.portfolio.model.cpp:42

• m_model_proxy->setDynamicSortFilter(true);

This property make Qt dynamically recalculate the whole sorting/filtering each time a bunch of coins are added, and this actions can be slow if repeated too often.

Few ideas how to solve that:

• At construction, set this property to false
• When the number of active coins reach the number of enabled coins, re-enable it to true
• If the user require to add too much coins at once (let's say more than 20) then we need to turn off this property to off again, and post enabling, re-enable it + resort.

can you take care of that @SylEze ?

With property to true:

Enregistrement.de.l.ecran.2021-09-01.a.11.36.33.mov

With property to false (no filtering - no sort):

Enregistrement.de.l.ecran.2021-09-01.a.11.38.13.mov

Balance from enable works great, seen as soon as added to list.

that's resolving the problem of indefinitely hang of app startup with a lot of assets

however, there are two more problems which we need to resolve @SylEze @Milerius :

1. if you start the app with 100-200 assets app became unresponsive/hangs for 30 seconds or so
2. when there are a lot of assets there is a loading spinner on tabs switching to the dashboard
