chore: type shim for csv-parse/lib/sync (TS7 compat)

[ggazzo]

Summary

Type-only shim so the CSV importers typecheck under TypeScript 7 — reworked after CI caught a runtime crash in the first approach.

What happened

The original PR switched the imports from csv-parse/lib/sync to the exports-declared csv-parse/sync. Typecheck and plain-node resolution were green, but the production Meteor bundle crashed at boot (Error: Cannot find module 'csv-parse/sync', run 29833170912) — the Meteor bundler resolves npm requires by physical path and doesn't support package exports subpaths. The legacy csv-parse/lib/sync specifier exists precisely because of that.

Fix

Keep the runtime specifier untouched and bridge only the types, following the existing definition/externals pattern:

declare module 'csv-parse/lib/sync' {
	export * from 'csv-parse/sync';
}

csv-parse/lib/sync isn't in the package's exports map (which TS7's resolution enforces), while csv-parse/sync carries a proper types condition — so the ambient declaration satisfies TS7 without changing what the bundler loads.

Verification

• TS7 probe (bundler resolution): import of csv-parse/lib/sync + shim → 0 errors
• TS5 (current toolchain): 0 errors
• Zero source/runtime changes — production bundle identical to develop

Part of the TS7-readiness set. Also supersedes the old branch content (the importer files moved to server/lib/import/ in the backend restructure; branch rebuilt on current develop).

Summary by CodeRabbit

• Bug Fixes
  • Improved compatibility when importing CSV parsing functionality, preventing related TypeScript resolution issues.
