fix(fresh-ui): key ChartBlock lists + correct Toast setTimeout ref type (#206)

• Issue: fix(fresh-ui): registry ChartBlock + Toast fail deno lint/check when copied into a Deno app #206

key={i} works for satisfying JSX key requirements, but if ticks/data can ever be inserted/reordered/filtered between renders, index keys can cause Preact to reconcile the wrong DOM nodes (e.g., bars/labels “swap” while keeping prior state). Consider using a stable value-based key (e.g., tick, or a stable datum identifier) when available.
