tdf#124339 fix HTML import of nested lists with mixed ol/ul types

When HTML contains sibling nested lists at the same depth but with
different types (e.g., an <ol> followed by a <ul> inside the same
parent list), the second nested list incorrectly inherited the first
list's numbering type. This happened because a single SwNumRule was
shared across the entire list hierarchy, and once a level's format
was set, it was never updated for a different list type.

Fix by detecting when a nested list's type conflicts with the existing
format at that level, creating a new SwNumRule with parent-level
formats copied over, and restoring the original rule when the nested
list closes.
