## Problem
When `NODE_ENV` is development, the server was only using the dev public
key to verify enterprise JWTs. Production keys are signed with the
production private key, so they failed verification with the dev public
key, resulting in "Invalid enterprise key" errors.
## Solution
Try both production and dev public keys when in development, so
production keys work when testing locally. In production, only the
production key is used (unchanged behavior).
## Changes
- `enterprise-plan.service.ts`: Replaced `getPublicKey()` with
`getPublicKeysToTry()` that returns both keys in development; updated
`verifyJwt()` to try each key until one succeeds
- `enterprise-plan.service.spec.ts`: Added test for production key
acceptance when `NODE_ENV` is development
