connectors: quieter chips, 3-line descriptions, single access-grant surface

Row descriptions clamp at three lines instead of one. Metadata chips
(scope/type/auth) lose the loud accents — only status chips keep colour —
and the auth chip speaks human ("Requires an API key") instead of the
raw enum, via a shared authLabel().

Drop the access-grant section from the connector detail page: the Users
page modal already grants both global and per-user connectors, so
"who has what" now has a single surface.
