feat: add auto furniture interaction detection

- New auto-interaction.ts: detects canSit/canLay/canStand from classname/name keywords
- Maps keywords to interaction types (bench, chair, bed, table, etc.)
- Returns clickLimit and interactionModesCount for proper click/interaction limits
- Nitro editor: added auto-detect button with preview of detected settings
- furni-import.ts: auto-sets interaction_modes_count during import
- upload-import.ts: auto-detects for direct insert and SQL migrations
- clone-import.ts: auto-detects when cloning from other hotels
