Adam Moussa ab9569d7a9 test: add ProposalNumberGenerator, LineItemService state guard, and API client interceptor tests
- ProposalNumberGenerator tests (8 tests): format validation (SHI-YYYY-NNNN),
  sequence incrementing, revision skipping, year boundary isolation, uniqueness,
  zero-padding, high sequence rollover. Uses SQLite in-memory with Postgres
  function stubs to support ExecuteSqlRawAsync.

- LineItemService state guard tests (18 tests): verifies line items cannot be
  created/bulk-updated/deleted on Approved or Sent proposals (QA-C2), confirms
  operations succeed on InReview and Revised statuses, validates
  KeyNotFoundException on missing proposals, verifies audit logging.

- API client interceptor tests (14 tests): request interceptor attaches Bearer
  token from sessionStorage (WEB-C1), handles missing/malformed token data,
  response interceptor dispatches Redux logout on 401 (WEB-M2), returns friendly
  messages for 403/404, extracts server error details, handles network errors.

- DbContextFactory updated to suppress InMemoryEventId.TransactionIgnoredWarning
  so BulkUpdateAsync tests work with in-memory provider.

- Added SqliteDbContextFactory for tests requiring relational features.

- Added Microsoft.EntityFrameworkCore.Sqlite to test project dependencies.

Total: 104 .NET tests (was 77), 26 web tests (was 12). CI already wired.
