Feature: Human-Readable Text Format Product Import
Implemented a new text-based import format for bulk product imports that is
easier to read, write, and version control compared to CSV format.
## New Features
### Import Service (ProductImportService.cs)
- Added `ImportFromHumanTextAsync()` - Main text format parser
- Added `GenerateTemplateAsHumanText()` - Template generator
- Parser supports:
- Product blocks starting with `#`
- Descriptions between `<text>` tags (optional)
- Key-value properties (category, price, weight, unit, stock)
- Variants (lines starting with `-`)
- Multi-buy offers (lines starting with `+`)
- Variant collections (optional, after product name)
### Admin UI
- New controller actions:
- `ImportText()` - GET: Show import form
- `ImportText(textContent, file)` - POST: Process import
- `DownloadTextTemplate()` - Download .txt template
- New view: `ImportText.cshtml`
- Textarea for pasting text
- File upload for .txt files
- Format documentation sidebar
- Links to CSV import and template downloads
- Updated `Index.cshtml` with dropdown menu for import options
### Template & Documentation
- Created `docs/ProductImportTemplate.txt` with 7 example products
- Demonstrates all format features:
- Products with/without descriptions
- Variants with stock levels
- Multi-buy pricing tiers
- Multiple weight units
