Manage Kits as embedded panel, fix checksum zero-padding mismatch

Manage Kits now opens inside the editor pane (like Properties and Link
View) instead of a separate Toplevel window. Also normalize hex
checksums by stripping leading zeros so .kit and manifest filenames
that disagree on padding (e.g. 462d43e vs 0462d43e) still resolve to
a version.
