fix(block2): clearer market states — 'can't reach servers' (retry) vs 'set your area'

Feedback: the market sometimes looked 'disabled'. Now the offline/empty states
are distinct and honest:
- No working relay (defaults exist, so it's a reachability issue) → 'Can't reach
  the community servers right now' + a Retry.
- Online but no area set → 'Set your area' prompt (you'd otherwise see a bare
  'nothing nearby').
- Area set + nothing found → the existing empty state.

i18n en/es/pt; offline tests updated; analyzer clean.
