ui: aggregated read on top, hide stale rows, wire /log tone toggle; prompts v8

- dashboard grid: explicit "header" area as the first row so the
    aggregated read panel renders at the top instead of being
    auto-placed after the named areas.
  - indicators: hide rows flagged stale (older than the group's
    freshness threshold). Server still computes stale_symbols;
    rendering can be re-enabled by removing the
    `{% if not is_stale %}` wrapper in indicators.html.
  - /log: add tone-changed to #log-content's hx-trigger and include
    it in cassandraSetTone's selector list — toggling Novice /
    Intermediate on the Log page was previously a no-op.
  - prompts: bump PROMPT_VERSION 7→8. Strengthen the rational-vs-
    irrational framing in the strategic-log system prompt from
    aspirational to mandatory ("a paragraph without both lenses must
    be rewritten"). Require the same lens in the per-group summary,
    cross-asset aggregate, and portfolio commentary overrides.

+irrationality. This is the single most important lens of the log — it MUST \
+appear in every sector or theme paragraph, not just where it feels natural. \
+For each paragraph, before writing it, ask yourself the two questions and \
+then make both answers visible in the prose:
+- The RATIONAL drivers — what the underlying factors justify: earnings, \
+real-economy data, monetary policy, structural geopolitical shifts, \
+valuation vs fundamentals.
+- The IRRATIONAL drivers — what the crowd is doing regardless of fundamentals: \
+positioning, narrative momentum, sentiment extremes, concentration, \
+flow-driven moves, options gamma, credit complacency.
+Then state the GAP: is price moving with the rational read, ahead of it, \
+or against it? If they agree, say so briefly and move on. If they diverge \
+— price moving on irrational drivers while fundamentals say otherwise, or \
+vice versa — name the divergence explicitly. Those gaps are where the next \
+regime change starts and are the whole point of this log.
+A paragraph that names only price action or only fundamentals, without \
+both lenses, is incomplete and must be rewritten.
