fix(IT): merge 2 dedup pairs flagged by #1395 remap (#1349 follow-up)

[dr5hn]

Summary

Resolves the two duplicate pairs explicitly deferred by PR #1479 because neither half carried the modern ISTAT-canonical merged-comune name. Both merges happened on 2017-01-01 under regional law and have new post-merger Wikidata items.

Pair MN (state_code=MN)

• Renamed id 60744 Sermide → Sermide e Felonica (name + native)
• Set wikiDataId to Q39681 (canonical merged-comune item; was null)
• Dropped id 138474 Felonica (absorbed into the merger; Q42389 retained on Wikidata as historical-comune entity)

Pair PV (state_code=PV)

• Renamed id 138065 Corteolona → Corteolona e Genzone (name + native)
• Set wikiDataId to Q3702780 (canonical merged-comune item; was Q40346 for the legacy Corteolona-only entity)
• Dropped id 138905 Genzone (absorbed; Q39697 retained on Wikidata as historical-comune entity)

Counts

• contributions/cities/IT.json: 9,941 → 9,939 rows (−2, as expected)

Notes

• Both kept rows verified to carry the correct state_code (MN, PV).
• bin/scripts/sync/normalize_json.py reported the file already normalized; no ID/timestamp churn needed.
• Diff is surgical (7 insertions / 89 deletions) — only the four targeted records changed.
• Refs [Bug]: Italy seems to be totally wrong #1349 and fix(IT): drop 6 duplicate pairs flagged by remap (#1349 follow-up) #1479. Does not close [Bug]: Italy seems to be totally wrong #1349 — additional cleanup items remain.

Test plan

• PR validator passes (schema, cross-ref, coordinates, duplicates, source URLs)
• Round-trip JSON → MySQL → JSON matches
• No remaining rows with name in {Sermide, Felonica, Corteolona, Genzone} in IT.json

contributions/cities/IT.json:104189

• After renaming this city to "Sermide e Felonica", the translations block still contains the old name (e.g., it, en-equivalents, etc. are still "Sermide"). This makes the record internally inconsistent and will surface incorrect localized names to consumers. Please update the translations to the merged comune name (or remove entries you can't confidently translate).
  contributions/cities/IT.json:283441
• This record is renamed to "Corteolona e Genzone", but the translations values are still for the pre-merge name "Corteolona" (including the Italian it translation). This introduces incorrect localized output for the merged comune. Please update translations to the merged name (or remove any languages you cannot verify).
