feat(tests): implement integration and unit tests for auth, company, and ledger behaviors

- Auth: 30 tests (97 assertions) covering OAuth, sessions, JWT, impersonation, roles
- Company: 35 tests (92 assertions) covering profile, 1099, expense reports, permissions
- Ledger: 113 tests (148 assertions) covering grid, journal entries, import, reports
- Fix existing test failures in running_balance, insights, tx, plaid, graphql
- Fix InMemSolrClient to handle Solr query syntax properly
- Update behavior docs: auth (42 done), company (32 done), ledger (120 done)
- All 478 tests pass with 0 failures, 0 errors
