Add KioskIntakeOutput company setting and fix kiosk submission bugs

- New CompanyPreferences.KioskIntakeOutput setting ("Quote" default / "Job"): controls
  what the kiosk creates on submission; shown as a card-style radio toggle in
  Company Settings → Kiosk tab
- KioskSession.LinkedQuoteId added so quote-first sessions link back to the draft quote
- Migration AddKioskIntakeOutputSetting applies both schema changes
- ProcessSubmissionAsync branches on setting: creates Draft quote (quote-first) or
  Pending job (job-first); save order fixed (CompleteAsync before using DB-assigned Id as FK)
- Terms.cshtml pricing paragraph is now dynamic: "subject to formal quote" for Quote mode,
  "team member will reach out about pricing" for Job mode
- Customer Intakes list: "View Quote" button appears when LinkedQuoteId is set
- Notification label fixed: Remote sessions now say "Remote Intake", not "Walk-in Intake"
- Inactivity reset shortened to 45 s on intake steps
- Signature pad: hosted locally (no CDN), canvas resize deferred via requestAnimationFrame
- AI photo upload: client-side compression to ≤1200px + AbortController 120 s timeout
- Help article and AI knowledge base updated with kiosk feature
