Adds the screen after onboarding: pick a month/year (ConfirmMonth), show
loading screens while the device is queried, then download that month's
records and resolve each distinct employee's name, printing both to
stdout (debug pretty-print) before landing on the placeholder "done"
screen.
- r701: RecordIterator's boxed stream is now Send, required for it to
cross into a Tauri command's future.
- oxibadge: load_records/load_employees commands, sharing the existing
3-retry connect_with_retries helper. load_records uses skip_while/
take_while on the device's newest-first stream to grab only the
target month without walking its whole history, then a single
collect + in-place Vec::reverse() back to chronological order.
- Shared LoadingScreen/Intro components extracted so future screens
reuse the same look without duplicating markup/CSS.
