internal/postgres: optimize unit metadata lookup for unknown module paths

When a user requests a package with a symbolic version (e.g., @master)
and the module boundary is not yet known, pkgsite currently triggers
a "greedy" index scan on the modules table's series_path index to find
the best match.

This change optimizes the lookup by explicitly providing candidate
module paths using internal.CandidateModulePaths. This allows the
Postgres optimizer to perform efficient point lookups on the
module_path index rather than a linear scan.

Fixes golang/go#77367
