Overview
Tags module — tenant tag-type catalog (under canonical companies/{company}/config/tags/types namespace) plus entity-agnostic tag assignments, batch operations, and reports. POLYMORPHIC: any model using HasTags + registered in config/tags.php (customer, customer_location, work_order, equipment, lead, opportunity) can be tagged through this single API. Client always sends entity_type (stable string key) + entity_id (UUID); the server resolves to the morph class internally. Same tag cannot be assigned twice to the same entity within a tenant (unique index enforces idempotency).
