Subject: [PATCH] =?UTF-8?q?Fix=20historical=20chart=20blank=20=E2=80=94=20?=
 =?UTF-8?q?ISO=20time=20strings=20rejected=20by=20LightweightCharts?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The historical runner stores equity curve times as ISO strings like
"2026-07-05T07:00:00" but LightweightCharts only accepts Unix timestamps.
Chart was loading 721 data points but rendering blank because time values
were silently rejected.

Changes:
- renderBTDetail: convert string times to Unix timestamps before setData()
- openDetail: same conversion for live/paper detail charts
- pushEquity: same conversion for main area equity charts

All chart codepaths now handle both string ISO and numeric timestamps.
