fix(spec): enforce ViewFilterRuleSchema operator enum + typed sort

- `operator`: z.string() → z.enum([equals, not_equals, contains,
  not_contains, starts_with, ends_with, greater_than, less_than,
  greater_than_or_equal, less_than_or_equal, in, not_in, is_empty,
  is_not_empty, is_null, is_not_null, before, after, between])
  so the SchemaForm renderer auto-generates a Select dropdown instead
  of a generic text input.
- `sort`: z.union([z.string(), z.array(...)]) → z.array(...) only.
  The union form confused the RepeaterField, causing it to render no
  UI at all for the sort sub-field.
- Updated a test fixture (task.view.ts) and share-link object
  (sys-share-link.object.ts) to use valid operators / array sort.
- Fixed spec tests to match the new enum (this_quarter → is_empty,
  gte → greater_than_or_equal, string sort → array sort).
