Updated intro flow

[concordium-cl]

Task description

The current introduction flow can be a bit confusing, so a new one should be made.

Some parts of the intro flow will still be the same, i.e. Splash screen, T&C, passcode + biometric pages and the "choose import" option. These screens have been kept in the sketched flow to keep some context, but they have been made semi-transparent so they can be easily seen.

In some of the screens late in flow, specifically those that are "after" the intro flow, you will be able to see some nice-to-have changes, or some need-to-have changes that are part of other issues.

Need-to-haves from other issues:

• Redesign account cards
• Updated "totals areas"
• Updated navigation bar

Nice-to-haves with separate issues:

• Flat ID cards with coloured edges depending on status.

Feel free to reach out to @jens-concordium if you are in doubt of need-to-haves vs. nice-to-haves.

The complete new intro flow can be seen in "Flow 7: The new intro flow" in Figma.

Notes:

• Some text bits will be underlined. These text bits have links to our documentation website.
• The text is now left aligned in the intro flow.
• "Flow 7.1" is a small extra flow shown in the lower right corner of the Flow 7 box. 7.1 shows how the backup banner takes priority over the "pending id" banner, when a new second account is pending.
