Fix Grid cache invalidation for multi-run task operations

[bggwak]

Problem

Grid UI was not updating after clearing or patching task instances when
using the include_future or include_past options.(#55267 )

Solution

• Fixed cache invalidation logic to properly refresh all affected DAG runs,
  not just the current run.
• Considered precise invalidation based on past/future options, but this
  required overly complex predicate logic.
• Opted for a simpler approach: invalidate all DAG Grid data whenever
  multiple runs are affected.

Code looks good, CI is not happy, you might need use the spread operator instead to set or unset the runid variable.
