fix: include local variable dot notation params in `grind?` suggestions (#12224)

This PR fixes a bug where `grind?` suggestions would not include
parameters using local variable dot notation (e.g.,
`cs.getD_rightInvSeq` where `cs` is a local variable). These parameters
were incorrectly filtered out because the code assumed all ident params
resolve to global declarations. In fact, local variable dot notation
produces anchors that need the original term to be loaded during replay,
so they must be preserved in the suggestion.

Closes #12185
