Harden multi-tenant isolation across all user-facing controllers

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.
