-- Migration: fix create_company_with_owner overload ambiguity
--
-- Background: 20260331010000_teams_table_refactor.sql defined the canonical
-- 4-arg signature:
--   create_company_with_owner(p_name text, p_entity_type text,
--                             p_set_active boolean DEFAULT true,
--                             p_team_id uuid DEFAULT NULL)
--
-- 20260519154732_seed_default_cash_account.sql then issued a CREATE OR REPLACE
-- with a 3-arg signature (dropping p_team_id) to add cash_accounts seeding.
-- CREATE OR REPLACE only matches when the parameter list is identical, so the
-- 3-arg form was created as a *new* overload rather than replacing the 4-arg
-- one. Both functions now coexist in production and both can be called with
-- two args (the third has a default), so PostgREST cannot resolve the call
-- and returns 300 Multiple Choices for any 2-arg invocation — breaking
-- /api/sandbox/seed (POST /rpc/create_company_with_owner failed with 300).
--
-- Fix: drop the 3-arg orphan and re-create the canonical 4-arg version with
-- the cash_accounts seeding merged in.
