fix(config): ANALYSIS_VISION_MODEL reader + compose RHS-interpolation test (0.87.17)

Browse Source 
Two ship-blockers from the rereview:

1. Env var name mismatch: 0.87.12 renamed every operator surface to
   ANALYSIS_VISION_MODEL but the reader still called env::var on
   ANALYSIS_MODEL — every documented deploy ran analysis with an
   empty model. Rename the reader.

2. Compose regression test was substring-only and missed exactly the
   ANALYSIS_VISION_MODEL vs ANALYSIS_MODEL RHS mismatch from 0.87.12.
   Tightened to require each backend-consumed var either be in a
   small hardcoded allowlist (BIND_ADDRESS, STORAGE_DIR) or have its
   RHS interpolate `${KEY...}` with the same name. Mutation-confirmed.
