feat: Ask for personal info before a transfer

[ptbrowne]

In some cases, we will want to ask the user some information
before allowing transfers.

• The myself io.cozy.contacts is checked to see that the birth city
  and nationality are present
• If not, the PersonalForm asks for the data and updates the myself contact
• The personal form can be displayed in two flavors depending on the page.
  It can be in a "Page" in the transfer page tab : when present, the
  transfer stepper is hidden, and the form takes its place. It can also
  be in a modal because it can be also accessed from the settings.

🚩 The "banks.transfers.need-personal-information" flag controls

• If the personal information section is available in the settings
• If personal information is asked before a transfer
