1) UpdateRuleAreasInScreens() is going to reset the rule
area caches on all SCH_RULE_AREAs. This means that every
SCH_ITEM in the screen that *had* a rule area cache is going
to get it cleared. So we might as well just up-front clear
the caches of all SCH_ITEMs, avoiding the need to use the
(possibly stale) pointers inside SCH_RULE_AREA::m_items.
2) UpdateRuleAreasInScreens() also sets the repaint flag on
all SCH_DIRECTIVE_LABELs, so there's no need to worry about
them elsewhere.
3) SCH_RULE_AREA::m_prev_items could also contain stale
pointers. We avoid this one by converting it to KIIDs.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/21120
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
