feat: display coinbase amount, other misc

Closes #5
Addresses #6

changes:
 * field Mining Reward --> Coinbase. (actual reward)
 * add field Expected Coinbase  (expected/calced reward)
     this field only displays if different from actual coinbase.
 * add field Cumulative Proof-of-Work
 * change tooltip 🛈   -->  ⓘ .  for mobile devices. (hopefully)
 * css: make tooltip text bold, so the ⓘ  is stronger.
