Spike detection now requires a move to clear an absolute floor AND (once
there's enough price history) be a configurable multiple of that
instrument's own recent typical move — MARKET_SPIKE_VOLATILITY_MULTIPLIER,
_recent_volatility() in markets.py — so a routinely volatile instrument
needs a bigger move to register than a normally-calm one, instead of one
fixed percentage for everything. Falls back to the floor alone until
there's enough history.
Economic Incident History: each incident gets two lazy-loaded overlay
charts (all tracked instruments, and just the incident's own), each
instrument normalized to % change from the window start so they're
comparable despite very different price scales/currencies — makes it easy
to see whether a move was isolated or broad, and to spot counter-reactions.
Backend: /api/markets/history now accepts an explicit start/end window
alongside the existing hours= param.
