cleanup: wrap console.log calls behind window.DASHCADDY_DEBUG flag

Wrapped 22 console.log calls across 6 files with a debug() helper
that only logs when window.DASHCADDY_DEBUG is true in the browser console.

Files:
- tour-manager.js: 10 calls
- theme-adapter.js: 4 calls
- keyboard-shortcuts.js: 4 calls
- tooltip-definitions.js: 2 calls
- progress-tracker.js: 1 call
- live-events.js: 1 call

console.error and console.warn calls preserved — those indicate
real issues worth seeing in production.
