feat(licenses): double confirmation modals for permanent deletion (#391)

Replace link-action delete buttons with show-modal pattern that opens
a Fomantic UI modal with a form. Package deletion requires typing
the package name in a required field before the submit button works.
Key deletion shows a warning modal with confirmation.

Uses Gitea's existing form-fetch-action + modal_actions_confirm
pattern, matching how repo deletion works in settings.

Both repo and org templates updated with matching modals.
