fix: standardize CSV export filename format to use project name

Unified export filename format across both ExportCSV and ExportConfigCSV:
- Format: YYYY-MM-DD (project_name) config_name BOM.csv
- Use PriceUpdatedAt if available, otherwise CreatedAt
- Extract project name from ProjectUUID for ExportCSV via projectService
- Pass project_uuid from frontend to backend in export request
- Add projectUUID and projectName state variables to track project context

This ensures consistent naming whether exporting from form or project view,
and uses most recent price update timestamp in filename.

export: implement streaming CSV with Excel compatibility

Implement Phase 1 CSV Export Optimization:
- Replace buffering with true HTTP streaming (ToCSV writes to io.Writer)
- Add UTF-8 BOM (0xEF 0xBB 0xBF) for correct Cyrillic display in Excel
- Use semicolon (;) delimiter for Russian Excel locale
- Use comma (,) as decimal separator in numbers (100,50 instead of 100.50)
- Add graceful two-phase error handling:
  * Before streaming: return JSON errors for validation failures
  * During streaming: log errors only (HTTP 200 already sent)
- Add backward-compatible ToCSVBytes() helper
- Add GET /api/configs/:uuid/export route for configuration export

New tests (13 total):
- Service layer (7 tests):
  * UTF-8 BOM verification
  * Semicolon delimiter parsing
  * Total row formatting
  * Category sorting
  * Empty data handling
  * Backward compatibility wrapper
  * Writer error handling
- Handler layer (6 tests):
  * Successful CSV export with streaming
  * Invalid request validation
  * Empty items validation
  * Config export with proper headers
  * 404 for missing configs
  * Empty config validation

All tests passing, build verified.
