Add Packages tab, hint view, Run it and signing key unlock

Packages tab over the helper inventory: query bar with cat:/maint:/
req:/status: prefixes, overlay and status chips, check column, and a
detail pane with versions, dependencies after hints and a structured
read-only view of the hint (hints.py mirrors slackrepo's parser).
Actions start slackrepo previews; the Jobs tab offers Run it with a
publish box (default from [builds] publish), asking for the signing
key passphrase first when the key is locked. Status bar shows the key
state; Dashboard tiles open their tabs; inventory reloads after
slackrepo and publish jobs.
