fix(lan-client): compact phase pills, wrap NEXT PHASE/NEXT TURN labels

The phase track (BEGIN · MAIN 1 · COMBAT · END) was losing labels to
ellipsis on narrow top bars, and the primary action buttons were
clipping "NEXT PHASE"/"NEXT TURN" because they had white-space: nowrap
and a fixed height.

.phase-step:
  - tighter padding (1px 5px) and gap (2px)
  - no letter-spacing, smaller border-radius, flex-shrink: 1 so pills
    compress uniformly when the top bar is crowded
  - merged duplicate .phase-step.active rule and made it bolder so the
    active step still reads well after the shrink

.btn-phase (NEXT PHASE / NEXT TURN):
  - white-space: normal + word-break: break-word enable two-line wrap
  - height: auto + min-height: 34px lets the label breathe inside
    the 44px top bar
  - min-width: 64px / max-width: 80px keeps the buttons square-ish
  - display: flex centers the wrapped text vertically & horizontally
  - align-items: stretch on .top-bar-actions so both buttons match
    the tallest sibling's height
