resource quota review: fix OOM risks, close quota gaps, add HA protections
Phase 1 - OOM fixes:
- dashy: increase memory limit 512Mi→1Gi (was at 99% utilization)
- caretta DaemonSet: set explicit resources 300Mi/512Mi (was at 85-98%)
- mysql-operator: add Helm resource values 256Mi/512Mi, create namespace
  with tier label (was at 92% of LimitRange default)
- prowlarr, flaresolverr, annas-archive-stacks: add explicit resources
  (outgrowing 256Mi LimitRange defaults)
- real-estate-crawler celery: add resources 512Mi/3Gi (608Mi actual, no
  explicit resources)

Phase 2 - Close quota gaps:
- nvidia, real-estate-crawler, trading-bot: remove custom-quota=true
  labels so Kyverno generates tier-appropriate quotas
- descheduler: add tier=1-cluster label for proper classification

Phase 3 - Reduce excessive quotas:
- monitoring: limits.memory 240Gi→64Gi, limits.cpu 120→64
- woodpecker: limits.memory 128Gi→32Gi, limits.cpu 64→16
- GPU tier default: limits.memory 96Gi→32Gi, limits.cpu 48→16

Phase 4 - Kubelet protection:
- Add cpu: 200m to systemReserved and kubeReserved in kubelet template

Phase 5 - HA improvements:
- cloudflared: add topology spread (ScheduleAnyway) + PDB (maxUnavailable:1)
- grafana: add topology spread + PDB via Helm values
- crowdsec LAPI: add topology spread + PDB via Helm values
- authentik server: add topology spread via Helm values
- authentik worker: add topology spread + PDB via Helm values

[ci skip] phase 5+6: update CI pipelines for SOPS, add sensitive=true to secret vars
Phase 5 — CI pipelines:
- default.yml: add SOPS decrypt in prepare step, change git add . to
  specific paths (stacks/ state/ .woodpecker/), cleanup on success+failure
- renew-tls.yml: change git add . to git add secrets/ state/

Phase 6 — sensitive=true:
- Add sensitive = true to 256 variable declarations across 149 stack files
- Prevents secret values from appearing in terraform plan output
- Does NOT modify shared modules (ingress_factory, nfs_volume) to avoid
  breaking module interface contracts

Note: CI pipeline SOPS decryption requires sops_age_key Woodpecker secret
to be created before the pipeline will work with SOPS. Until then, the old
terraform.tfvars path continues to function.

[ci skip] add auto-generated tiers.tf, planning docs, and helm chart cache
- tiers.tf: Terragrunt-generated tier locals for all standalone stacks
- .planning/: resource audit research and plans
- docs/plans/: cluster hardening design doc
- redis-25.3.2.tgz: Bitnami Redis Helm chart cache

[ci skip] Flatten module wrappers into stack roots
Remove the module "xxx" { source = "./module" } indirection layer
from all 66 service stacks. Resources are now defined directly in
each stack's main.tf instead of through a wrapper module.

- Merge module/main.tf contents into stack main.tf
- Apply variable replacements (var.tier -> local.tiers.X, renamed vars)
- Fix shared module paths (one fewer ../ at each level)
- Move extra files/dirs (factory/, chart_values, subdirs) to stack root
- Update state files to strip module.<name>. prefix
- Update CLAUDE.md to reflect flat structure

Verified: terragrunt plan shows 0 add, 0 destroy across all stacks.

[ci skip] Move Terraform modules into stack directories
Move all 88 service modules (66 individual + 22 platform) from
modules/kubernetes/<service>/ into their corresponding stack directories:

- Service stacks: stacks/<service>/module/
- Platform stack: stacks/platform/modules/<service>/

This collocates module source code with its Terragrunt definition.
Only shared utility modules remain in modules/kubernetes/:
ingress_factory, setup_tls_secret, dockerhub_secret, oauth-proxy.

All cross-references to shared modules updated to use correct
relative paths. Verified with terragrunt run --all -- plan:
0 adds, 0 destroys across all 68 stacks.

[ci skip] Phase 3: Create 66 service stacks and migrate state
Generated individual stack directories for all 66 services under stacks/.
Each stack has terragrunt.hcl (depends on platform) and main.tf (thin
wrapper calling existing module). Migrated all 64 active service states
from root terraform.tfstate to individual state files. Root state is now
empty. Verified with terragrunt plan on multiple stacks (no changes).
