deploy(fc-llm-bridge): roll fc:vision image v202604300022

Source: FlowerCore.LlmBridge@8dd181c (feat: fc:vision route + image
content forwarding). Adds:

- fc:vision tier alias parsing (TryParseTier handles fc:vision,
  FC:VISION, openai/fc:vision, vision)
- Image content forwarding: OpenAi image_url shape (https URL +
  data:[mediaType];base64,... URI) and Anthropic image/source
  passthrough are now promoted to LlmContentBlocks. Text-only
  content-parts arrays still flatten to the legacy joined string.
- DefaultRoutes seeder + appsettings.json gain Vision -> Anthropic +
  claude-sonnet-4-6.

Image built on BLUEJAY-WS, podman save + ctr import to all 3 RKE2
nodes (rke2-server, rke2-agent1, rke2-agent2). Bridge tests: 62/62
green (was 51/51, +11). Backwards-compatible with current chat /
util / embed callers; existing routes unchanged.
