Non-production environments (development/testing) now force the
effective tenant to the reserved test tenant "llm_tester" (or a
test_-prefixed override) regardless of DEFAULT_USER misconfiguration:
- Config.effective_default_user only honors DEFAULT_USER outside
production when it is llm_tester or test_-prefixed; anything else
is forced to llm_tester (tenant_forced flags the override)
- Config refuses startup (validation error) when a non-production
environment is explicitly configured with the production tenant

- get_user() applies the same guard at request-context resolution,
so an explicit request for the production tenant in dev/test is
forced to llm_tester with a warning log
- initialize_application() emits one loud startup log line
(tenant_guard_active / tenant_guard_production) stating the
effective tenant
Unit tests cover the dev/test/prod x default/explicit-user matrix.
