feat: declarative GitOps config via Helm values + fsnotify watcher
Replace the CRD-based controller with a lightweight file-based approach that reads YAML config from a ConfigMap mounted at /etc/kite/config.d/. Key changes: - pkg/config/types.go: KiteConfig schema (OAuth, RBAC, GeneralSettings) - pkg/config/watcher.go: fsnotify watcher with conf.d merge, debounce, ConfigMap symlink support, and polling fallback - pkg/config/reconciler.go: full CRUD reconciliation to database with orphan cleanup and managed-resource tracking - main.go: replace CRD controller with file watcher startup - pkg/model/{oauth,rbac}.go: add ManagedBy field for tracking - charts/kite/: Helm templates for ConfigMap, volume mount, env var - deploy/examples/: Entra ID and conf.d usage examples Closes #226, #360, #233 Ref: maintainer feedback on PR #441 requesting Helm-only approach

# Declarative Configuration (GitOps-ready)
311+
# ══════════════════════════════════════════════════════════════════════════════
312+
# When enabled, the chart creates a ConfigMap mounted at /etc/kite/config.d/
313+
# containing YAML config files. Kite watches this directory with fsnotify and
314+
# reconciles OAuth, RBAC, and settings to the database automatically.
315+
#
316+
# Features:
317+
# - Hot reload: changes apply within seconds (no pod restart needed)
318+
# - conf.d pattern: multiple files are merged alphabetically
319+
# - GitOps native: works with ArgoCD, Flux, or any Helm-based pipeline
320+
# - No CRDs required: configuration is a simple ConfigMap
321+
# - Managed resources are tracked: manually-created resources are never touched
322+
# - Orphan cleanup: if you remove a provider/role from config, it gets deleted
323+
#
324+
# For OAuth client secrets, do NOT put them in values.yaml. Instead:
325+
# - Use a Kubernetes Secret and reference it via extraEnvs, or
326+
# - Use External Secrets Operator / Sealed Secrets to inject them
327+
# - The clientSecret field supports env var interpolation at runtime

## Usage with Helm:
4+
## helm upgrade --install kite kite/kite -f kite-values-entra-id.yaml
5+
##
6+
## Usage without Helm (standalone ConfigMap):
7+
## 1. Create the ConfigMap from this file:

## kubectl create configmap kite-declarative-config \
9+
## --namespace kite \
10+
## --from-file=oauth.yaml=deploy/examples/entra-id-oauth.yaml \

## --from-file=roles.yaml=deploy/examples/entra-id-roles.yaml

## 2. Mount it at /etc/kite/config.d/ in the Kite Deployment
13+
## 3. Set env KITE_CONFIG_DIR=/etc/kite/config.d (optional, it's the default)
14+
##
15+
## For OAuth secrets, create a separate K8s Secret and inject via env vars:
16+
## kubectl create secret generic kite-oauth-credentials \
17+
## --namespace kite \
18+
## --from-literal=CLIENT_ID=your-client-id \
