chore: pr review changes

Panel events identified the panel only by its legacy panel type, which
cannot tell apart two kinds that map onto the same one — so a newly added
kind is indistinguishable from the kind it shares a type with.

Adds panelKind alongside the existing panelType on all seven events (no
data, clone, delete, move, CSV export, drilldown opened, create alert).
Additive on purpose: existing reports keep resolving.
