fix(dashboard): clear container cache on focus, deprecate applyDagreLayout

setFocusNode was missed in the C1 cache-reset pass. Focus mode narrows
filteredGraphNodes to focus + 1-hop neighbors, so a container that
survives still has a subset of its children — the cache must drop
or it'll keep returning positions for filtered-out ids.

Mark applyDagreLayout @deprecated. The structural views all use ELK
now; the helper is retained for one release as a quick fallback path
and removed in the next.
