Fix container hash-prefix + status-aware redeploy

Bug 1: Container name hash-prefix (e.g. f93cb8b504f7_jenkins)
- _strip_hash_prefix(): strips 12-char hex prefix and leading slash
- _resolve_container_name(): looks up actual DSM name from container list
- Applied in list_containers (display), container_stats (matching),
  get_container_status/get_container_logs/exec_in_container (lookup)

Bug 2: redeploy_project DSM 2101/1202 on wrong project state
- Fetch project status before acting
- RUNNING     → stop then start
- STOPPED     → start directly (nothing to stop)
- BUILD_FAILED → suppress stop error, then start
- Other       → return error with workaround hint

36 tests all passing.
