/api/backtest now annotates each replay trade with the live loop's realized
P&L for the same (session, symbol) and returns a live_split summary (taken vs
not-taken n/sumR/avgR). Page grows two summary cells, a Live P&L column with
an amber ≠ marker when sim and live disagree on a trade's sign, and a footer
caveat: minute-bar granularity + adverse fills flip individual rows — trust
aggregates, not rows. Read-only annotation; cached replay result unchanged.

Owner saw a blank /backtest — it was CORRECT (the regime gate sat out every
recent session) but unexplained. Now: ?regime=0|1 override on /api/backtest,
an 'apply regime gate (as deployed)' checkbox, and an empty-state message
saying WHY there are no trades and what to click. Gated view = what the bot
would do; ungated = the raw simple criteria.

Adds a read-only /backtest page showing how the bot WOULD have traded past
sessions under the CURRENTLY configured live settings: theoretical ORB fires
from setup_events, replayed through the shared exit engine (simulate_exit +
ExitConfig.from_env(), same adverse-fill accounting the exit-experiment
harness uses), screened through the shared population gate and (optionally)
the live regime gate. No new simulation math — replay.replay_window() is pure
assembly of existing pieces (reconstruct_fires_from_setups, _fire_in_population,
_load_regime_favorable, simulate_exit); api/main.py adds the /backtest and
/api/backtest routes plus a dedicated-lock 10-min cache so a slow replay never
blocks the live dashboard's SSE stream. Also extends /api/chart with an
optional date= anchor so the trade drill-in chart modal can reach sessions
older than the existing 72h-from-now window, and adds a one-line BACKTEST nav
link to the live dashboard header.
