Rewrite legacy datatype to eZ Platform field type
summary
A working eZ Platform field type replaces the legacy eZ Tags datatype by reimplementing the Tag value object, the Field Type, a Legacy storage converter + Gateway, and a Tag service so tags are readable, writable and indexable. Templates and service YAML register the type, and reverse-engineer eZ Tags uncovers the DB schema and settings. The implementation uses fromHash/toHash serialisation, stores data in legacy tables, renders tag lists in Twig, and updates content programmatically.
