Re-apply: seed all CSV entries, fix category mapping, add duplicate detection

Rebase had inverted ours/theirs, reverting our changes. Re-applying:
- normalizeSpaces() for non-breaking space fix in category mapping
- Remove isValidEntry filter, include all CSV rows for AI screening
- Duplicate submission detection in stage-filtering (always flags, never auto-rejects)
