[store_yaml] Drop dead re-resolve and duplicated SECRETS_FILES check

`track_yaml_loads` already returns resolved Path objects, so re-wrapping
each entry in `Path(...).resolve()` was a no-op. The OR'd
`Path(path).name in SECRETS_FILES` branch always evaluated the same as
the first check on the resolved name; removing it. Document the symlink
edge case the resolver swallows so a future change to the loader can
revisit it.
