Fix passkey login tracking, add email opt-out UI guards, and add Quick/Full quote mode toggle

- PasskeyController: set LastLoginDate on passkey sign-in so Company Health
  and audit pages show accurate last-login times (was always showing 'Never')
- Jobs/Index status modal: disable 'Notify customer' email toggle and show
  warning when customer has notifications turned off; CustomerNotifyByEmail
  added to JobListDto + JobProfile mapping + data-customer-notify attribute
- Quotes/Create: disable 'Send quote via email' checkbox with 'Notifications
  off' badge when selected customer has email opt-out; ViewBag.CustomerEmailOptOutIds
  added alongside existing CustomerTaxExemptIds pattern
- Quotes/Create: Quick Quote / Full Quote segmented toggle at top of form;
  hides non-essential fields (dates, notes, tags, oven, discount, photos) in
  Quick mode; selection persisted in localStorage
- InvoicesController Send action: improved error logging and user-facing
  warning when PDF generation or email dispatch fails after status is saved
- item-wizard.js: guard item restoration with try/catch; ensure writeHiddenFields
  always runs on form submit via capture-phase listener
- Help docs and AI knowledge base updated for all new features
