-- 010_tenants_fields.up.sql
-- M13b W1: Tenant (company) operational fields.
--
-- Adds the per-tenant knobs the admin UI needs to manage:
--
--   rate_limit_per_sec INTEGER
--     Cap on ingest events/sec for this tenant. Default 10000 (the
--     value used in v1 everywhere). Enforced by the ingestion
--     pipeline per-tenant (the per-tenant key is a known pattern;
--     the existing M1/M4 ingest uses company_id from the event).
--
--   fcm_shared BOOLEAN
--     When true, this tenant's FCM traffic uses the shared HTTP/2
--     pool (the default in M8+). When false, future code can pin
--     this tenant to a dedicated sender ID. Read by deliverd-fcm
--     when picking a sender. W1 only persists the flag; the
--     read-side is wired in M13b W3 (Telegram) where the same
--     multi-tenant pool isolation story lives.
--
-- The migration is safe to apply to a populated DB — both columns
-- have defaults that match what M13a W1-W5 code already expected
-- (no behavior change for existing rows).
