App for kid

[ka8725]

This is an epic task because this feature is going to be big but it should bring huge value. Moreover, seems we can't launch without it. Too many potential users requested it (on problematic interviews conducted - https://trello.com/b/PjqR5KxK/interviews).

We should create a separate page that will be later used as an entry point for the mobile app. Note, we won't have a landing page for the mobile app at all because it doesn't make sense. The landing page is only for web.

The page should provide a choice for the user:

• "I'm a parent"
• "I'm a kid"

"I'm a parent" choice leads to the /my_account path (for not logged-in users it will redirect to login).

"I'm a kid" choice leads to a screen that asks to enter a pairing key that's provided by his parents. Once this is entered the kid has access to their account. The access is limited. A kid can to only these actions:

• read all
• create "-" transactions (so that when they receive cash or buy something with parents help, they can enter this transaction themselves, parents will receive a notification about that so they can validate it - the notification is already implemented so we don't need to do anything in regards of that)
• manage goals
• create "+" transactions with parents approval (following the same logic as above that parents receive emails about transactions it becomes safe action, but we need to add an easy functionality for parents to amend this transaction)
• edit account: name, avatar, bg image (we will add it)

@VladislavSokov let's add the "+" button here too.
