fix: eliminate duplicate module tabs and whitespace-variant finding rows

- Module tabs: check if a module already exists as a dataset tab kind
  before creating a mod: tab, preventing duplicate sidebar entries.
- Finding dedup: collapse repeated whitespace in target/finding strings
  so slightly different spacing (e.g. '= ' vs ' =') is deduped as same row.
