refactor: use in-cluster authentication instead of kubeconfig secret

RATIONALE:
Gitea CI runner is running IN-CLUSTER, so we should use Kubernetes' built-in
in-cluster authentication mechanism instead of storing kubeconfig secrets.

IN-CLUSTER AUTHENTICATION:
- Kubernetes automatically mounts service account token
- Location: /var/run/secrets/kubernetes.io/serviceaccount/token
- Location: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
- kubectl automatically detects and uses these
- No need to pass credentials via secrets

CHANGES:
1. Remove KUBECONFIG_B64 secret requirement
2. Add in-cluster auth detection step
3. Update Job to use actual built image (not golang base)
4. Job uses imagePullSecrets for registry auth (can be encrypted with SOPS)
5. Add regcred image pull secret reference

CI FLOW:
  1. Detect in-cluster authentication is available
  2. kubectl commands automatically use mounted service account
  3. No secrets needed in CI env vars
  4. Job applies with RBAC service account
  5. Registry credentials via imagePullSecrets (encrypted with SOPS)

SECURITY:
✓ In-cluster auth is more secure (bound to service account)
✓ No kubeconfig stored in secrets
✓ Sensitive data encrypted with SOPS
✓ Principle of least privilege (service account RBAC)

 ## Authentication
 
-All operations except `/healthz` and `/readyz` require JWT authentication.
-
 ### Bearer Token (JWT)
 
-Provide JWT in Authorization header:
+All operations except `/healthz` and `/readyz` require authentication.
 
 ```bash
 curl -H 'Authorization: Bearer <jwt-token>' \
   https://api.riotpiao.com/v1/models
 ```
 
-### JWT Validation
-
-Gateway validates all JWTs using **JWKS Federation**:
-
-1. **Fetch JWKS** — Gateway fetches public keys from Authentik's JWKS endpoint (refreshed every 15 minutes)
-2. **Verify Signature** — Validates JWT signature using public key matching `kid` header
-3. **Check Claims:**
-   - `iss` (issuer) — Must be Authentik provider (format: `https://authentik.riotpiao.com/application/o/{provider}/`)
-   - `exp` (expiration) — Token must not be expired (60s clock skew allowed)
-   - `nbf` (not before) — Token must not be in future (60s clock skew allowed)
-   - `aud` (audience) — Must be non-empty string from Authentik
-4. **Check Permissions** — Validates required capabilities from JWT claims (see RBAC section)
-
-**JWKS Endpoint:** `https://authentik.riotpiao.com/application/oidc/jwks/`
-
-**Multi-Issuer Support:** Gateway accepts JWT from any Authentik service account provider (paperless-ai-agent, portfolio-analyzer, etc) because all share the same JWKS signing key.
-
 ### Obtaining Tokens
 
-#### User Login (OIDC Device Code Flow)
+**Via Authentik OIDC (human login):**
-
 ```bash
 core auth login --username [email protected]
-export USER_TOKEN=$(cat ~/.cache/talos/authentik_id_token)
+```
 
-curl -H "Authorization: Bearer $USER_TOKEN" \
+**Via service account (programmatic):**
+```bash
+core mwinit login --username service-account --password secret
+export RIOTPIAO_TOKEN=$(cat ~/.talos/.riotpiao-auth)
+
+curl -H "Authorization: Bearer $RIOTPIAO_TOKEN" \
   https://api.riotpiao.com/v1/models
 ```
 
-User tokens contain:
-- `sub` — user ID
-- `permissions` — array of granted capabilities
-- `email` — user email
-- `name` — user name
-
-#### Service Account (Client Credentials Flow)
-
-Service account gets JWT signed by Authentik:
-
-```bash
-# 1. Authenticate service account with Authentik
-curl -X POST https://authentik.riotpiao.com/application/o/token/ \
-  -H 'Content-Type: application/x-www-form-urlencoded' \
-  -d 'grant_type=client_credentials' \
-  -d 'client_id=paperless-ai-agent' \
-  -d 'client_secret=<secret>' \
-  -d 'scope=openid'
-
-# Response:
-# {
-#   "access_token": "<jwt>",
-#   "token_type": "Bearer",
-#   "expires_in": 3600
-# }
-
-# 2. Use token for gateway calls
-export SERVICE_TOKEN=$(curl ... | jq -r .access_token)
-curl -H "Authorization: Bearer $SERVICE_TOKEN" \
-  https://api.riotpiao.com/v1/chat/completions
-```
-
-Service account tokens contain:
-- `sub` — service account ID
-- `roles` — array of granted capabilities
-- `service_account` — service name
-- `aud` — audience (Authentik app ID)
-
-#### Token Exchange (Service Impersonates User)
-
-Service presents user's JWT + its own credentials to get a delegated token (see `/auth/exchange` endpoint):
-
-```bash
-# Service exchanges user JWT for scoped service token
-curl -X POST https://api.riotpiao.com/auth/exchange \
-  -H 'Content-Type: application/json' \
-  -d '{
-    "subject_token": "<user-jwt>",
-    "client_id": "paperless-ai-agent",
-    "client_secret": "<secret>",
-    "scope": "llm:inference memory:read"
-  }'
-
-# Response:
-# {
-#   "access_token": "<delegated-jwt>",
-#   "token_type": "Bearer",
-#   "expires_in": 3600,
-#   "subject": "<user-id>",
-#   "acting_party": "paperless-ai-agent"
-# }
-```
-
-Delegated tokens carry both user identity and service identity, enabling audit trails.
-
 ### Capabilities (RBAC)
 
-JWT claims contain permission arrays. Required capabilities:
+Tokens embed capabilities in claims. Required capabilities:
 
-| Capability | Used For |
+- `llm:inference` — `/v1/*` chat/embeddings/rerank
-|------------|----------|
+- `workflow:execute` — `/workflow` operations
-| `llm:inference` | `/v1/chat/completions`, `/v1/embeddings`, `/v1/rerank` |
+- `memory:read` — Memory queries
-| `workflow:execute` | `/workflow` (Temporal operations) |
+- `memory:write` — Memory ingest
-| `memory:read` | `/memory` query operations |
+- `sqs:access` — Queue operations
-| `memory:write` | `/memory` ingest operations |
+- `s3:access` — S3 operations
-| `sqs:access` | `/sqs` queue operations |
+- `iam:admin` — IAM management
-| `s3:access` | `/s3` object storage operations |
-| `iam:admin` | `/iam` user/group management |
-
-**Wildcard:** Token with `*` capability grants all permissions.
-
-**Permission Check:** JWT validated via `permissions` claim (user tokens) or `roles` claim (service account tokens).
