Follow-up to #2982. The platform-agent build failed at RUN chmod +x with Operation not permitted because platform-tenant runs as non-root. Replaced both COPY+RUN chmod pairs with COPY --chmod=0755. EMPIRICALLY VERIFIED: manual buildx FROM platform-tenant:staging-latest now completes all layers (push only blocked by cross-account ECR perms on the build host; CI publish runner has prod-account perms). This is the last fix to make the concierge identity image actually build.

After #2982 repointed the concierge image to FROM platform-tenant (the live
base), the build failed at `RUN chmod +x` with "Operation not permitted":
platform-tenant runs as a non-root user, so a build-time RUN chmod can't set the
+x bit (the dead molecule-ai/platform base was root, which masked this).

Replace both `COPY + RUN chmod +x` pairs (identity-fallback.sh and the
/entrypoint-platform-agent.sh heredoc) with buildx-native `COPY --chmod=0755`,
which sets the executable bit at copy time regardless of the base USER.

Empirically verified: with this change the platform-agent image builds cleanly
FROM platform-tenant:staging-latest (manual buildx run completed all layers;
only the push was denied due to cross-account ECR perms on the build host — the
CI publish runner has the correct prod-account principal).
