feat(api): pagination on GET product prices (closes #47)

Browse Source 
- GET /api/v1/products/{id}/prices now returns PagedResult<ProductPriceDto>
  with OFFSET/FETCH + COUNT via Dapper (two queries on same connection)
- Query params: ?page (default 1) and ?pageSize (default 20, max 100)
- Clamping: Math.Max(1, page) + Math.Clamp(pageSize, 1, 100) in handler
- Auth upgraded from [Authorize] to [RequirePermission("catalogo:productos:gestionar")]
- IProductPriceRepository.GetByProductIdAsync signature updated to paginated form
- AddProductPriceCommandHandler adapted to read back via page=1, pageSize=2
- TDD cycle: RED (tests updated to PagedResult shape) -> GREEN (implementation) -> REFACTOR
- Tests: 1418 total (1106 Application + 312 Api), 0 failures

closes #47
