Added explicit CompanyId == companyId predicates to every tenant-scoped
query in 22 controllers so cross-tenant data leakage is impossible even
if EF Core global query filters are bypassed or misconfigured.
Also fixed ApplicationDbContext.IsPlatformAdmin to correctly return true
for SuperAdmins with no CompanyId claim (break-glass accounts) and when
no HTTP context is present (background services, unit tests), resolving
225 unit test failures that stemmed from the global filter blocking all
in-memory test data.
New MultiTenantIsolationTests class (8 tests) verifies the explicit
predicate layer independently of the global query filters.

- AccountingDropdownHelper: wired into BillsController and ExpensesController,
replacing 35-40 lines of duplicated DB queries per controller
- AppConstants.StatusCodes: added Job.* and Quote.* constants to replace all
magic status strings across Jobs, Quotes, Appointments, OvenScheduler,
AiQuickQuote, QuoteApproval, and AccountingDropdownHelper
- AccountingRules: extracted IsNormalDebitBalance into shared Infrastructure
helper; removed duplicate private method from AccountBalanceService and
LedgerService (~50 lines deleted)
- AccountDataExportController: extracted 9 Fetch*Async methods (superset of
includes) so Add*Sheet and Build*Csv no longer duplicate DB queries; each
entity is queried once regardless of whether XLSX or CSV format is requested
- BillsController.Create and ExpensesController.Create wrapped in
ExecuteInTransactionAsync; blob uploads moved after commit to keep
financial data atomic and prevent orphaned blobs from rolling back
- Number generators (Appointments, CreditMemo, OvenBatch) fixed from full-table
GetAllAsync to prefix-filtered FindAsync
