webui/collector: strip ANSI escapes in nvidia-smi topo parsing, auto-prepare drives for RAID mirror creation

Browse Source 
- nvidia-smi underlines the topo -m header with ANSI CSI codes even when
  writing to a file; both NVLink matrix parsers failed to find the header
  and /topo showed "No NVLink-bonded GPU pairs found" on bonded systems.
- raid-lsi-create-mirror failed with "resources already in use" (exit 11)
  on JBOD drives; the task now reads drive states and auto-converts
  JBOD/UBad (set good force), releases hotspares, refuses Frgn/Onln with
  actionable messages, and dumps preservedcache info when add vd fails.
