Set quote status to Converted and show job number link on quote details

- CreateJobFromQuote now sets QuoteStatusId to CONVERTED after creating the job
- Added ConvertedToJobNumber to QuoteDto, populated in Details action
- 'View Job' button on Quote Details now shows the job number (e.g. 'View Job JOB-2505-0001')
