feat(import): add CSV bulk import for notes

Add client-side CSV parsing and bulk import API endpoint for importing
notes from CSV files. Supports quoted fields, newlines in values, and
escaped quotes.

- New POST /api/decks/{deckId}/notes/import endpoint for bulk creation
- CSV parser with RFC 4180 compliance
- Multi-phase import modal (upload → validate → preview → import)
- Client-side validation with per-row error reporting
