initially set out to add the failed tooltip back to the transaction list, but
in the process rediscovered the transaction-status component which illuminated
a fair number of statuses that were not properly handled by the refactor of the
list. These statuses were discussed with UX and engineering team members to come
up with a definitive list of statuses that should be reflected in the UI
Changes:
1. normalized the color of status labels to use Red-500 and Orange-500 where applicable
2. added a new color of icon for pending transactions -- grey
3. added support for dropped and rejected labels
4. failed, dropped, rejected and cancelled all have red icons now.
5. cancelled transactions will reflect a change in the user's balance
6. tooltip displayed for failed transactions
7. Icon logic isolated to a new component.
