prosolis d87536c879 Fix bugs found in local testing
- Dashboard auto-refresh rendered the full layout into its own
  refresh container, producing a duplicate sidebar every 60s; it now
  renders only the body partial.
- 'Run Now' runs synchronously with a bounded timeout and returns
  refreshed results plus success/error feedback, instead of
  firing-and-forgetting with no signal.
- Price-history chart data moved from a <script> block to a data-
  attribute: templ does not interpolate expressions inside <script>
  element content, so the JSON was emitted literally.
- The htmx indicator spinner was permanently visible due to CSS
  source order; the indicator rules now follow .v-spinner.

Also refreshes README for this session's changes.

// Renders the price-history line chart on the per-item results page.
// Chart data is read from the canvas's data-chart attribute: templ
// interpolates attribute values but treats <script> element contents as raw
// text, so the JSON cannot live in an inline <script> block. Loaded after
// chart.umd.min.js with the #price-chart canvas already in the DOM above it.
