Phase 1: Fix all critical release blockers (B1-B10)

B1: Remove duplicate get_redis() — singleton no longer overwritten
B2: Plugin routes now enforce activation status via require_active_plugin()
B3: Fix UploadFile ForwardRef error — remove functools.wraps from wrap_plugin_route
B4: DMS upload uses true streaming via save_stream() instead of RAM accumulation
B5: Worker on_startup registers plugin event handlers + webhook dispatcher
B6: Implement send_password_reset_email job, remove raw token logging
B7: Webhook SSRF protection (IP validation, no redirects), secret removed from response
B8: RLS repair migration 0044 + separate crm_runtime DB user (NOSUPERUSER, NOBYPASSRLS)
B9: Fix .env.docker.example AUTH_SECRET → SECRET_KEY
B10: Remove Redis default password, remove exposed DB/Redis ports

Also: add frontend_url to config, add SMTP settings to .env.docker.example,
update prestart.sh to use MIGRATION_DATABASE_URL for alembic.
