List of recent operations can be confusing for users

[bartekn]

In the list of transactions we display payments only (create_account, payment, path_payment and account_merge). It can be confusing for users that use the same key to make trades in other apps as the final balance does not match the balance when you track payment by payment. (The other thing is that XLM balance won't match anyway as we don't display fees associated with each payment.)

I think we should at least display information near XLM balance that it's normal that it does match the list and why.

I think a small copy addition is a good solution to this. Maybe add to

This tool is hiding payments smaller than 0.5 XLM.

so it says

This tool is hiding payments smaller than 0.5 XLM and only displays payment operations.
