stripe-java appears to be unused in this repository (no references found under backend/src/**). Keeping it as a runtime dependency (and upgrading it across major versions) adds unnecessary transitive dependencies and potential classpath conflicts. If Stripe is not actually used, consider removing this dependency; if it is used indirectly, consider adding/pointing to the integration point so future upgrades can be validated.
