chore(dashboard): retire the V1 variable runtime

The V1 variable engine had no writers left: nothing wrote selectedValue, so
getDashboardVariables produced undefined values, variableFetchStore was never
updated, and the dependency graph and derived store fields only fed that store.
The shared store's one remaining job is publishing the open dashboard's dynamic
variables for query-builder autocomplete, which needs a name and an attribute.

Replace it with a suggestion feed and delete the rest, including the panel
variables prop that no GridCard caller passed and useResolveQuery's dashboardData
option that no caller supplied. useGetResolvedText loses its only variable source
and becomes the title truncation its callers already used it for.
