refactor(js): extract import/export module from app.js monofile (§3.1)
Third slice of the app.js split. Moves the encrypted export container, CSV/JSON import parsing (parseCSV, findColumn, parseEntriesFromCSV, parseEntriesFromJSON), and the doImport/doExport/doExportCSV flows to js/app.import.js. encryptImportEntry moves here too (also called by app.sync.js — resolved via shared global scope at call time). - Byte-for-byte identical to the extracted block; no duplicate const; no top-level import ref left in app.js. - Load order: BEFORE app.js (pure declarations, no top-level side effects), alongside app.crypto.js. Full order: argon2 → crypto → import → app → sync. - index.html + BuildAssets whitelist + harness APP_PARTS updated. - Safety net: the 14 CSV tests exercise parseCSV/parseEntriesFromCSV from the extracted file and stay green (42/42). app.js: 11936 → 10253 lines (crypto + sync + import now separate, ~1700 lines moved into 3 modules). NOTE: assets.res not regenerated here (needs brcc32/Delphi) — run BuildAssets before the next Delphi build to embed js/app.import.js. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
