frontend: finish the dashboard comment-density sweep

Continues #3901 (dashboard round 1 was #3906, tabs.js/swarm.js).
Scanned the rest of packages/dashboard/src for the same 'moved to X'/
'now lives in Y' pattern: five more hits in schedules.js, common.js,
logs.js (two, one duplicating the other), core.js, and swarm.js.
All trimmed to state the current location as a fact rather than
narrating the move; one inline duplicate (logs.js's tab-default
comment restating the file-header pointer) dropped outright.
