fc-ttsreader: bump image to v202605061500 (Phase 4delta enrichment pipeline)

Phase 4delta server-side HTML overlay enrichment landed in
FlowerCore.TtsReader@8f23e15 (master @6091618). Adds 9-pass enrichment +
SQLite-backed cache + 4 REST endpoints (/api/v1/enrich/{html,jsonld,both,passes})
+ RenderRequest.sourceJsonLd. Tests 476 -> 522 (+46). Image already imported
to all RKE2 nodes via deploy.sh; this bumps the bluejay-infra-managed tag so
ArgoCD reconciles the live deployment.
