Phase 2: Eliminate ApplicationDbContext from domain controllers

Migrated InvoicesController, QuotesController, JobsController, BillsController,
PurchaseOrdersController, and CustomersController to route all data access
through IUnitOfWork typed/generic repositories instead of injecting
ApplicationDbContext directly.

New typed repositories added: IJobRepository (GetScheduledJobsForDateAsync,
GetActiveJobsForMobileAsync, LoadForCostingAsync), INotificationLogRepository
(GetLatestForJobAsync, GetAllForJobAsync), IQuoteRepository (GetItemsWithCoatsAsync
with CatalogItem eager load + AsNoTracking), and IJobRepository.GetOrphanedConversionJobAsync.

All EF complex include chains relocated into repository methods; controllers now
call named query methods rather than composing raw IQueryable chains.
