fix(v2): drop an inert field from the document tag-filter scope

resolveKnowledgeTagFilters builds every structured filter with the stored
definition's fieldType and never reads the caller's — not for resolution, not
for validation, not in its output. Fingerprinting it made a field the query
ignores decide whether a cursor resumes, so adding or removing a matching
fieldType refused a page that had not moved.

Swept the other twelve cursor-scope routes for the same shape. No scope part
is absent from its mapInput, this was the only scope carrying a structure
resolved against stored state, and knowledge/search has no cursor at all.
