feat(askai): add Kapa.ai source group filtering for InfluxDB v3

- Add ai_source_group_ids field to all InfluxDB v3 products in data/products.yml
- Add getProductSourceGroupIds() function to retrieve source group IDs from product data
- Enables filtered AI responses using Kapa source groups for documentation pages
- Follows existing pattern for dynamic product configuration
- Implement version-specific config support (__v1, __v2 suffixes)
- Append version hints to example questions for InfluxDB database products only
- Make example questions generic (remove product-specific names)
- Tools (Telegraf, Chronograf, Kapacitor, Flux, Explorer) display questions without version hints
- Pre-fills chat input with [version: /path/] for InfluxDB database products
- Users can easily edit or remove the pre-filled text
- Works for manual opens (Cmd+K) and programmatic opens
- Converts module to TypeScript
