fix: resolve environment variables on application rollback

rollbackApplication() called prepareEnvironmentVariables() without the
environment env, so every ${{environment.*}} reference threw "Invalid
environment variable: environment.X" and the rollback failed with an
opaque 400 before the swarm service was updated.

fb749cd86 added the third argument to every other call site but left
services/rollbacks.ts, which had been calling the helper since 24bff9689.
The value is already captured in the snapshot by createRollback(); both
fullContext declarations simply typed environment as { project: Project },
so the missing argument was invisible to the compiler.
