[FEATURE] Load icons from backup

[biagio11]

Please confirm the following:

• I've checked the current issues for duplicate issues.
• I've requested a single (only one) feature/change in this issue. It complies with the One Request Per GitHub Issue (ORPGI) rule.
• My issue is well-defined and describes how it should be implemented from UI/UX perspective.

What do you want to be added or improved?

If all the data is lost, removed from the device, or migrated to a new device, I would like the category icons to load and show correctly when loading the data. As for now when loading data from backup from scratch it shows the default icon "category" for the categories and the "account" for the accounts.

I looked into the .json file and I can see that the categories are saved with an "icon" label so it should be an easy fix.

Why do you need it?

• To have a better user experience if files are lost or device gets changed.

How do you imagine it?

Simply load and show the user the correct icons once the data is loaded from backup from scratch.

Hey @biagio11 did you try "Backup Data" and not CSV. I think the JSON backup preserves the icons?

Can you attach a demo video where you repro this bug?

I imported from the actual Ivy Wallet backup.

I can try to understand and find the issue in the code.
I suspect it is related to the data quantity (performance issue?) as with a small test case it seems like it won't happend.

If the behaviour is not expected we should consider it a minor bug.

I'll keep you updated!

Unfortunately, I'm unable to replicate the issue consistently.
When I try so, sometimes only a few categories display with the "category" icon, while at other times they show correctly. Occasionally, none of the categories appear at all.

During my tests, I noticed that the app occasionally crashes when completely deleting the data. This might be related to the performance issue #2965.

The data may be correctly read but not immediately shown/refreshed.

I'm loading >400 entries of data from the Ivy Backup (i.e., JSON file).

To figure out the issue, does someone know where the data gets loaded in the app structure/logic so that we can start looking into it?
