Consolidate the sticky-Manual rule for oneliner.json into a single helper paths::delete_oneliner_unless_manual that holds the per-case lock, reads the state, keeps OnelinerState::Manual, and removes any LLM-derived variant. Three previously-direct deletion paths now route through it: handle_delete_recording, reset_case_artefacts (admin single-reset), and bulk_reset (admin bulk action). Before this fix a clinician's manual override was wiped by a recording delete, letting the LLM auto-regen path overwrite it on the next view. Tests: 4 unit tests for the wrapper contract, integration tests for the recording-delete and case-reset endpoints (Manual preserved, Ready wiped), and a static-scan invariant that fails on direct remove_file(... ONELINER_FILENAME) calls outside paths.rs.
