fix: make debug mode toggle work at runtime

The debug/insecure warning banner was only controlled by the compile-time
DEBUG constant. The settings easter egg checkbox toggled state.debugMode
and the runtime log flag, but neither index.js nor helpers.js checked
these runtime values — the banner was created/updated based solely on
the compile-time constant.

Changes:
- Extract banner logic into updateDebugBanner() in helpers.js that
  checks isDebug() (combines compile-time DEBUG and runtime debugMode)
- Banner is dynamically created/removed: appears when debug is enabled,
  removed when disabled (no stale banners)
- index.js init() syncs runtime debug flag from persisted state before
  first render, then delegates to updateDebugBanner()
- settings.js calls updateDebugBanner() after the checkbox change so
  the banner immediately reflects the new state
- Debug mode persists across popup close/reopen via state.debugMode

Fixes the bug where the settings debug toggle had no visible effect.
