Hide email controls when no email on file; show SMS hint for quote/job events

- Quotes Create/Edit: hide 'Send via email' checkbox when customer has no
  email; show badge 'send via SMS from details' or 'SMS consent required'
  when customer has a mobile number. JS responds to customer dropdown change.
- Quotes Details: hide 'Send Quote via Email' button and approval email
  checkbox; hide SMS button when no mobile; show consent-required note.
- Jobs Details (Mark Complete modal): hide email checkbox; show
  'SMS notification will be sent' badge or consent-required note.
- Jobs Index (status modal): hide email row when customer has no email.
- Jobs Edit: hide 'Notify customer if status changes' when no email.
- Invoices Details: hide Send/Re-send buttons when no email (vs. disabled).

DTOs: added CustomerEmail + CustomerNotifyByEmail to JobDto/JobListDto;
added CustomerNotifyByEmail/CustomerMobilePhone/CustomerNotifyBySms to
QuoteDto. Mapped in JobProfile and QuotesController customer blocks.
