Add RecordTick — a permissionless instruction that reads the current tick from a CurrentTickAccount and advances a PriceObservations ring buffer. Authorization is implicit: both PDAs are verified against price_source_id, so the tick can only have been written by whoever controls that price source. A sampling guard silently no-ops if less than `window_duration / OBSERVATIONS_CAPACITY`` ms have elapsed, allowing keepers to call blindly on every block. Tick-delta truncation clamps the per-observation delta to `MAX_TICK_DELTA (9 116)` before advancing tick_cumulative, with last_recorded_tick tracking the untruncated position for the next delta. Also switches ObservationEntry.tick_cumulative to use elapsed milliseconds rather than seconds. Closes #116
