infra: provision Kapsule cluster in fr-par with GPU support
Move all infrastructure from nl-ams to fr-par-2 for H100 GPU availability.
Kapsule cluster provisioned with 3 node pools (always-on DEV1-M, CI GP1-XS,
GPU H100-1-80G), databases deployed (Postgres/TimescaleDB, Redis, QuestDB),
and Tailscale subnet router configured.
Key changes:
- Region: nl-ams -> fr-par-2 (GPU types only available in Paris)
- K8s version: 1.30 -> 1.34 with auto-upgrade
- Block storage: migrate b_ssd -> SBS (scaleway_block_volume)
- Kapsule: add VPC private network, delete_additional_resources
- GPU pool: conditional via enable_gpu_pool variable
- K8s manifests: fix registry URLs, secret key names, PG subPath
- Add terragrunt cache/lockfile to .gitignore
