Disable leftover Reports and Clipboard session verbs

[baseGame]

Summary

Reports and Clipboard Compare still left a few Session/View verbs clickable even though those sessions never run them. The command palette also ignored the same enablement rules as the menus.

This change:

• Turns off unused compare/session verbs on Reports (compare, swap, reload, rules, settings, export, show all, minor, next difference).
• Turns off unused Clipboard Session items (rules, settings, export). Compare, swap, and reload stay on.
• Applies the same enablement to the command palette and refuses to run a disabled command from there.

Run Script and Save Report stay available on Reports. Text Merge four-pane and live Registry hive are still out of scope.
