Add github.com/hashgraph/solo-operator to solo-weaver go.mod

**Epic:** #1081

Add `github.com/hashgraph/solo-operator` as a Go module dependency in solo-weaver's `go.mod`, pinned to the version that introduces `pkg/jobs`. Import only the `pkg/jobs` sub-package — not the API types or controller packages.

```
go get github.com/hashgraph/solo-operator@v
```

## Acceptance Criteria
- [ ] `go.mod` and `go.sum` updated
- [ ] Only `pkg/jobs` sub-package imported (no `api/`, `internal/`, or `cmd/`)
- [ ] `go build ./...` passes
- [ ] `go mod tidy` leaves no changes

Start by checking solo-operator releases or module history to identify the version that introduced pkg/jobs. Update solo-weaver's go.mod and go.sum, ensuring imports remain limited to pkg/jobs, then run go build ./... and go mod tidy. Done means the build passes and go mod tidy leaves no changes.
