vjrj eb3aec82ae meteor3: purge dead client packages — web UI renders on 3.1
alanning:roles removed (client crashed the whole bundle; plain user.roles
checks instead), selaias:cookie-consent replaced by in-repo React banner,
publish-performant-counts vendored with countAsync, Meteor.autorun dropped
(App)/Tracker.autorun (FiresMap), and the map publications not covered by
the REST smoke (activefiresmyloc, activefiresunionmyloc, fireAlerts,
oauth.verifyConfiguration) converted to async APIs.

Verified in browser: / and /fires render with map + cookie banner, zero
uncaught exceptions. REST smoke byte-identical (12/12).
