The cron poll committed only at the end; with ~100 created receipts and a 1s
pause between Checkbox requests it hit arq's 300s timeout every run, so all
status updates were rolled back and fiscalized receipts stayed "created".
Now each run polls at most 30 least-recently-checked receipts and commits
after each one.

Checkbox relays Nova Poshta's "To many requests" (20000401501) as a 4xx
third_party.generic error, not a 429, so bursts of receipt requests ended
up as failed receipts. Such responses are now CheckboxRateLimitedError:
the receipt stays pending and the worker job is retried with arq.Retry
after the "Try again after N seconds" delay plus backoff. NP timeouts
relayed the same way are treated as unavailable (unknown outcome).
The HTTP client also sends Checkbox requests one at a time with a
CHECKBOX_MIN_REQUEST_INTERVAL_MS pause and signs the cashier in once for
concurrent jobs.

- ExoCrmClient.set_status: live SetStatus needs {Orders: [id], Status} and
replies per order, unlike the documented {ID, Status}
- receipts.crm_status_set_at (migration 0006); set right after creation,
retried by cron, row-locked to avoid a repeat PACKED overwriting a newer status
- CRM errors under capitalized 'Errors' and non-JSON replies are reported

- prepayment as DISCOUNT: live API rejects PRE_PAYMENT with 400 third_party.generic
- normalize lowercase ETTN statuses returned by the live API
- show Checkbox error code instead of bare 'Internal Server Error'
- page size 50 for ETTN list, 429 rate limit is retryable, pause polling on it
- phone in 380XXXXXXXXX format like portal receipts

Payments now carry type=ETTN / label=Експрес-накладна instead of relying on
Checkbox defaults; body build fails fast if goods - discounts - prepayment
does not equal the COD amount.

Cashier creates an ETTN receipt in Checkbox bound to the TTN with payment
control; Checkbox fiscalizes it itself when the parcel is paid for.
- cash_registers (Fernet-encrypted license key / PIN) and receipts tables
- Checkbox HTTP client + stub (ETTN does not work on test registers)
- two-phase create via ARQ job, timeout reconciliation, cron status polling
- /receipts and /cash-registers API, audit records
- dashboard: per-order and bulk create, prepayment, cancel; cash registers page
