copy: strip jargon from tool descriptions and captions

Prior round only touched page_caption; the description field (shown on
home grid cards) still said "imputation", "missingness",
"winsorization", "schema coercion", "fuzzy matching with normalization",
etc. The audience is non-technical buyers — they shouldn't need a stats
or DB-admin vocabulary to read a tool card.

Rewrite both description and page_caption across en, es, and the
tools_registry (the fallback source of truth) using everyday words:
blanks instead of nulls, fill in instead of impute, look wrong instead
of statistical outliers, etc. Same one-line shape as before.
