chore(deps): bump grpc and x/net to patch dependabot alerts

[robbycochran]

Resolves the two open dependabot alerts on main:

• HIGHgoogle.golang.org/grpc 1.81.1 → 1.82.1 — xDS RBAC and HTTP/2 vulnerabilities.
• MEDIUMgolang.org/x/net 0.51.0 → 0.55.0 — HTML parser DoS.

Both are indirect deps. go mod tidy also pulled the matching x/sys 0.42.0→0.45.0, x/text 0.34.0→0.37.0, and genproto/googleapis/rpc.

Test plan

go build ./..., go vet ./..., go test ./..., golangci-lint run ./... — all green locally.
