v1.3.5: reparse progress spinner + Today default on Home

- Re-parse ALL now shows a spinner + "Re-parsing all transactions…"
  while running, so taps don't feel ignored. Button is hidden during
  the work; reappears after the result line.
- Empty result (no transactions to re-parse) shows a hint pointing at
  "Import SMS history" instead of a confusing "0 of 0".
- Home period selector defaults to Today instead of Month — the spec
  showed Month first, but in practice users want to see today's
  spending at a glance and switch out only when needed.
