Admin Positions

Fleet-wide currently-OPEN positions with mark-to-market.

The /admin/trades feed is a history of CLOSED trades — one row per close. This endpoint fills the complementary need: what's still on the book right now, per bot, with unrealized P&L, target/stop levels, and time_stop_at so the operator can see at a glance how long a hold has been running and where the exits would fire.

Read-only, no filters, always returns all open rows across the fleet — a fleet has at most tens of concurrent positions in practice, so paging isn't needed.
