v1.34.2 — resilient crypto payment provisioning + dependency/security bumps

Crypto billing — resilient payment provisioning

Crypto Pro payments are now provisioned automatically when the received
amount is within a small tolerance of the invoice (covering exchange and
network rounding), instead of requiring an exact-amount settlement.
Genuine underpayments and failed/expired/refunded payments are left
unprovisioned and surfaced to operators. Amounts are validated from the
signature-verified provider notification.

Operational visibility

Operator notifications added for underpaid / failed / expired / refunded
payments and for successful key claims.

Dependencies / security

• cryptography 48.0.0 → 48.0.1 (GHSA-537c-gmf6-5ccf)
• beautifulsoup4 → >=4.15.0
