Completes the SLMM side of the L1/L10 live-display contract. The NL-43's DOD response carries percentile slots LN1-LN5 (channel 1, parts[5]/[6]); parse the first two and expose them as ln1/ln2 end to end: - NL43Snapshot dataclass: ln1/ln2 fields - NL43Status model: ln1/ln2 columns (+ migrate_add_ln_percentiles.py) - DOD parser: snap.ln1=parts[5], snap.ln2=parts[6] - persist_snapshot writes them - all /status data dicts, StatusPayload, and the DRD stream payload emit ln1/ln2 (null on the DRD stream itself, which doesn't carry percentiles) Labels: device LN1 defaults to L5, not L1 — Terra-View defaults the label to L1/L10, so the device's Ln1/Ln2 slots must be set to 1%/10% for the labels to be accurate (dynamic label emission is a follow-up).

Migration script to add ln1 and ln2 percentile columns to the nl43_status table.

The NL-43 DOD response carries percentile slots LN1-LN5; the live SLM display
|
|
(Terra-View) shows two of them (default L1/L10). This adds storage for the two
|
|
surfaced slots. Run once per database to update existing schema.
