fix(otc-bridge): scope high_24h/low_24h to the trailing 24h window

[Vyacheslav-Tomashevskiy]

Problem

GET /api/stats reports high_24h / low_24h, but computes them from the last 100 trades of all time:

prices = c.execute(
    "SELECT price_per_rtc_nano_quote FROM trades ORDER BY completed_at DESC LIMIT 100"
).fetchall()
...
"high_24h": max(price_list),
"low_24h":  min(price_list),

Meanwhile volume_24h_rtc in the same handler is correctly filtered with WHERE completed_at >= day_ago. So a price that last traded days ago is still reported as a 24h high/low.

Repro

Two trades: one 5 days ago @ 5.0, one 1 hour ago @ 0.1. In the last 24h only 0.1 traded, so both high_24h and low_24h should be 0.1, but the endpoint returns high_24h = 5.0 — while volume_24h_rtc in the same response correctly ignores the old trade.

Fix

Compute high_24h/low_24h with a MIN/MAX over WHERE completed_at >= day_ago (also drops the incidental 100-row cap on the extremes). last_price still tracks the most recent trade overall.

Test

Adds test_stats_high_low_are_24h_scoped asserting the actual values (the existing stats test only checked key presence). It fails on main, passes with the fix. (Note: the suite has pre-existing failures on main unrelated to this change — order-matching/escrow paths; the stats tests pass.)

LGTM — scopes high_24h/low_24h to trailing 24h window. ✅

[Scottcjn]

Verified, with a flag. The titled change is real but display-only: high_24h/low_24h used ORDER BY completed_at DESC LIMIT 100 (last 100 trades ever) instead of the trailing window, affecting reported stats only. That fix is sound and this app (otc_bridge gunicorn) is a standalone daemon, not the consensus node.

However the diff ALSO bundles an undescribed bridge_api refund-lock change that IS wired into the live node, which is a real fund-path change hidden under a stats-fix title. Please split that into its own PR (or reconcile with #7938, which is the canonical version of that hunk) so it gets its own review. Titled bug: merge. Bundled bridge change: split first.

The red CI is branch-staleness, not this change: the failing tests are the fetchall_guard baseline and miner-artifact checksum pins, which pass on clean current main (verified). Main regenerated those after this branch was cut, so a rebase onto main clears them.

[Vyacheslav-Tomashevskiy]

Split done — thanks for catching that, you were right that the bridge hunk had no business riding under a stats title.

This branch is now a clean cherry-pick of just the otc_bridge commit onto current main, so the diff is otc-bridge/otc_bridge.py + its test and nothing else. The refund-lock hunk is dropped here entirely; #7938 stays the canonical version of it, so there's no second copy to reconcile.

The rebase also picks up the regenerated fetchall_guard baseline and checksum pins, so the staleness reds should clear.

Test check on my side: test_stats_high_low_are_24h_scoped fails on clean main and passes with the fix. The other failures in that file are pre-existing on pristine main (they reproduce with the test file reverted), so they're not from this change.
