Jinwoo Hong 80d7e2dded fix(relay): spread drain placement over a load band instead of one empty cell (#26802) ...

* fix(relay): spread placement over a load band so a drain does not land on one empty cell

Placement took the single least-loaded cell, so a just-rolled cell took a
whole drain and every follow-up serialized on its relay_cells row. Directors
now pick at random among cells within 5% of capacity of the minimum, and skip
a cell that already took over 40% of its pool's placements in the last 10 s
(floor 4). It only reorders: the least-loaded cell is the fallback, the hard
cap and region preference are unchanged.

* fix(relay): size the load band's intake window for the 1,200 s drain pace

At ~0.5 picks/s per director, a 10 s window with a floor of 4 let the floor
decide and the empty cell took ~65% of a c27-sized drain. A 60 s window and
a floor of 2 keep it at 40% at both the 300 s and 1,200 s paces across five
directors. Adds a once-a-minute orca_relay_placement_load_band line (picks,
budget skips, fallbacks, band size, picks per cell).

* chore(relay): log the load-band summary at info, not warning
