Returns a paginated list of segment configurations.
This is how you discover a configId before passing it to Run Segmentation, and how you
check which segment definitions already exist before creating a duplicate.
Each item carries the full config definition, including its segments and their rules,
plus createdAt and updatedAt under meta.
Filter by filter[name] (case-insensitive contains match on name). Order with sort —
allowed fields: name, createdAt, updatedAt. Prefix the field with - for descending
order. Use page[number] (1-based) and page[size] (default 25, max 200) to paginate.
Returns 200 with a paginated array of segment config resources and JSON:API pagination
links. Returns 400 if filter, sort, or pagination parameters are invalid.
