raid: parse storcli64/storcli2's actual per-slot drive JSON shape

Browse Source 
RAID Controller Management showed "No drives detected" for a live
SAS3808-iMR controller even though storcli64 clearly enumerates its
drives. Root cause: the "eall/sall show all J" drive-listing parser
(collector/raid.go and its webui/raid_mgmt.go duplicate) assumed
drives are reported as a single "Drive Information" array, but real
storcli64/storcli2 output nests each drive under its own dynamically
named key ("Drive /c0/e69/s0", paired with a "... - Detailed
Information" key) — confirmed against a live techdump/storcli64-drives.json
capture. The assumed shape was never actually produced by the tool, so
this affected every storcli64/storcli2 controller, not just Tri-Mode
ones (the storcli2 fallback added in b7f015c never got a chance to
mask it in practice, since storcli2 itself reports zero controllers on
this hardware — a separate, unrelated tool-side gap).

Both parsers now read "Response Data" as a raw key map and pull drives
from either shape, so older storcli output using the array form still
works alongside the real per-slot form.
