fix(ashby): gate operation-specific param mappings to prevent stale overwrites

Multiple subBlocks share the same target tool param (createdAt is set by
appCreatedAt/candidateCreatedAt/noteCreatedAt; candidateId by appCandidateId/
filterCandidateId). Because subBlock values persist across operation switches,
a stale value from a prior operation could silently overwrite the correct one.
Guard each mapping with an explicit operation check.
