Member Library Platform 0.11.0

Redesigns the Access Groups page around two panels, Live and Draft: Live shows what members have now and when it was published; Draft lists exactly what would change and offers one action for its state (Review changes, then Publish or Back to editing). Every group card carries a Live / Changed / New badge and the membership editor shows when its draft differs from live. Publishing uses a normal confirmation dialog instead of a typed phrase; the server-side block on removing any member's access is unchanged. Includes 0.10.1 catalogue speed-up and 0.10.2 write-only revocation secret.
