v1.2.2 - Autosort, UI Polish & K8s Fixes

🚀 New Features

• Subnet Autosort: Subnets are now automatically sorted by IP address (CIDR) in the backend, ensuring a logical hierarchical display.
• UI Polish: Updated browser tab title to 'IPAM' and added a custom favicon (Black Pin with Blue IP).

🐛 Bug Fixes

• Login CORS / Mixed Content: Fixed login issues on Kubernetes by updating the frontend to use a relative API path (/api) and allowing CORS.
• Postgres Deployment: Fixed initdb error on Kubernetes by using a subdirectory for PGDATA and adding an init container to fix volume permissions.
• Health Probes: Fixed Kubernetes liveness/readiness probes by adding a public /api/health endpoint.

🐳 Infrastructure

• Images: All images updated on Docker Hub (moresophy organization).
