fix: update frontend to 2d7117a, admin to a13dce5, ai to 320e683

- frontend: use registry.nxtgauge.com/node:20-alpine
- admin: use registry.nxtgauge.com/node:20-alpine
- ai: use registry.nxtgauge.com/rust:1.87-alpine and alpine:3.20
- All images now use internal registry to avoid Docker Hub rate limits
- Update kustomization.yaml tags and admin base deployment image
- Remove ghcr.io references from admin gitops

Images needed in registry.nxtgauge.com:
- node:20-alpine
- rust:1.87-alpine
