- List individual account instead of account type under User & account

- Add handling to move account tiles with specific account type from
top level account dashboard to inside the corresponding account
preference.
- Rename settings.accounts.AccountPreference to
settings.accounts.AccountTypePreference to make it less confused
with settings.AccountPreference
