Add "ToS" and "Privacy Policy" links to Settings Screen.

When creating a wallet use can read terms and privacy policy.
After wallet is created there is no way to open it again. I think there should be links somewhere in wallet allowing opening it.

User Story

As a user that already has created an account and entered the wallet,
I want to have access to read the Terms of Service and the Privacy Policy links,
so I can consult them whenever I feel like it.

Acceptance Criteria

AC1. Inside the Settings screen (cog icon), in the list of options, and above "Delete all accounts", 2 links will be added. One labeled "Terms of Service" and another one labeled "Privacy Policy".
AC2. When a user taps on "Terms of Service" they will be directed to the same place as in the onboarding flow.
AC3. When a user taps on "Privacy Policy" they will be directed to the same place as in the onboarding flow.
AC4. User can close Terms of Service or Privacy Policy and return to the settings.

Important task after the new fork since we will definitely have new URLs.
