chore(deps): batch Dependabot bumps + ES2022 tsconfig (v0.17.1-beta)

Apply the open Dependabot updates as one validated batch (build + test + lint +
local Docker smoke test all green) rather than 11 separate merges.

Backend:
- @types/node 20.19.43 -> 26.1.1 (aligns types with the Node 26 runtime)
- typescript-eslint 8.58.2 -> 8.64.0
- eslint 10.5.0 -> 10.7.0
- eslint-plugin-security 4.0.0 -> 4.0.1
- nodemailer 9.0.1 -> 9.0.3
- tsconfig target/lib ES2020 -> ES2022 so Array.prototype.at() (devices.ts)
  type-checks under the new @types/node — this is what unblocked #72.

Frontend:
- axios 1.18.0 -> 1.18.1
- react-router-dom 7.18.0 -> 7.18.1
- lucide-react 1.21.0 -> 1.23.0
- @xyflow/react 12.10.2 -> 12.11.1
- @vitejs/plugin-react 6.0.2 -> 6.0.3

CI:
- docker/setup-qemu-action v3 -> v4
