PageRequest.of(0, 10_000) was inlined at ~12 sites across DocumentServiceTest and DocumentServiceSortTest as an "effectively unpaged" sentinel for tests that don't care about paging. Extracted to a named constant on each class so the intent is visible at each callsite and we don't risk copy-paste drift of the magic number. No behaviour change.
