fix(guacamole): add --- separator between macmini-vnc-creds OnePasswordItem and guacamole-branding ConfigMap

Missing document separator caused YAML to merge the OnePasswordItem's
top-level `spec: itemPath:` block into the ConfigMap that follows.
Result: a ConfigMap with a `.spec` field whose K8s schema does not
declare one, triggering ArgoCD's structured-merge diff to fail since
2026-05-11T15:30:54Z:

  Failed to compare desired state to live state: failed to calculate
  diff: error calculating structured merge diff: error building typed
  value from config resource: .spec: field not declared in schema

App stayed Healthy (live K8s tolerated the extra field — ConfigMap
ignored it) but ArgoCD's diff calc was broken, leaving the app stuck at
sync=Unknown for all 21 resources. Adding the missing `---` separator
makes the OnePasswordItem and ConfigMap proper sibling YAML documents,
each with its own kind-correct schema.

Diagnosed during 2026-05-12 morning routine.

+# fc-redis — SignalR backplane for cross-product event bus
+#
+# Lands per Q-SO-1 resolution (2026-05-11 PM): SignalR backplane in Phase A,
+# not Phase C as originally drafted. Operator directive: "Redis can be
+# deployed just fine as it's another FlowerCore technology we'll want to
+# manage."
+#
+# Phase A scope (this file):
+#   - Single Redis 7.x Alpine pod
+#   - 1Gi Longhorn RWO PVC for AOF persistence
+#   - ClusterIP Service at `redis.fc-redis.svc.cluster.local:6379`
+#   - No AUTH (in-cluster only; not exposed externally)
+#   - No IngressRoute (backplane is server-to-server only)
+#
+# Consumers (Phase A IMPL across FC services):
+#   - FlowerCore.Signage.Web (OpsConsoleHub)
+#   - FlowerCore.Scoreboard.Web (ScoreboardHub)
+#   - FlowerCore.SignalControl.Web
+#   - FlowerCore.DMS.Web
+#   - Any other product joining the cross-product event bus
+#
+# Each consumer adds:
+#   services.AddSignalR()
+#           .AddStackExchangeRedis(
+#               "redis.fc-redis.svc.cluster.local:6379",
+#               opts => opts.Configuration.ChannelPrefix =
+#                   StackExchange.Redis.RedisChannel.Literal("fc-opsconsole"));
+#
+# Phase B / C follow-ons (out of scope here):
+#   - Redis Sentinel for HA (3-node)
+#   - AUTH password from 1Password Connect (rotate via /rotate-password)
+#   - redis_exporter sidecar for Prometheus scrape
+#   - Network policies restricting which namespaces can dial 6379
+#
+# Design: docs/signage/operations-console-phase-2-design.md §3.5
+# Decision: Q-SO-1 (RESOLVED 2026-05-11 PM)
+# Memory: feedback_blooming_ui_pattern_no_iframes
