Live track record: score the committed signals with the backtest's accounting

[yanivil]

Summary

PR 1 of the website plan: the live track record has to use the same accounting as the replays, or the site's "what happened" table would not be comparable to the ten-year figures next to it (and to the late-entry table of #115).

Changes

• tools/evaluate_signals.py: the fill is the next session's open; an open above the row's Max buy (gap) or at or below the stop (below_stop) is not traded; an unresolved position past the horizon is expired at that bar's close, open means still running; R is measured from the fill. Rows carry fill, fill_date, exit_date, pnl_pct and the sessions on which the signal was listed (listings, listed_days, last_listed); the summary adds the not-traded counts and the total R; the table gains Listed, Fill, Exit and P&L % columns.
• fill_and_classify is the one implementation of the fill rules: the backtest's _fill_outcome now calls it (expire=False, the replay's convention), with results unchanged, which the existing backtest tests assert.
• Tests (141 pass), wiki 04, changelog. The evaluate-signals workflow itself is unchanged.

The six live signals under this accounting (run 34326465568 on this branch, bars through 2026-09-08)

Ticker	Pattern	Signal date	Listed	Entry	Fill	Stop	Target	Outcome	Bars	Exit	P&L %	R

Three stopped, three open, mean R −0.57 on six signals; the fills differ from the reported entries by under 1 %.

Test plan

• ruff --select E,F,W --line-length 120 clean, 141 tests pass locally
• evaluate-signals workflow run from this branch (34326465568)
• tests workflow on this PR
