Implement consistent Return to Rotation UX across all sites

This update provides a unified, predictable inactivity prompt behavior
regardless of how the user navigated to a page.

Changes:
- Added userInteractedWithCurrentSite flag to track user touch on each site
- Modified markActivity() to set flag when user interacts (tap, swipe, scroll)
- Modified attachView() to clear flag when site changes
- Updated inactivity check to use interaction flag instead of navigation mode

New Behavior (Consistent UX):

✅ Scenario A: Auto-rotation to recipe → user taps → prompt after timeout
   - Site auto-rotates to recipe page
   - User taps screen to scroll/interact
   - userInteractedWithCurrentSite = true
   - After 2 min idle → prompt appears
   - User can extend time or return to rotation

✅ Scenario B: User swiping through photos every 30 seconds
   - Each swipe resets inactivity timer via markActivity()
   - No prompt appears (user is actively interacting)
   - Prompt only appears after they stop swiping for timeout period

✅ Scenario C: Sites auto-rotating with no user interaction
   - userInteractedWithCurrentSite = false on each site
   - No prompt appears
   - Rotation continues normally

Technical Details:
- Single-finger swipes (in-page content): Reset timer via markActivity()
- Two-finger swipes (tab navigation): Also sets manualNavigationMode
- Both types of interaction trigger the flag
- Flag cleared on every site change (auto or manual)
- If manual swipe, markActivity() re-sets it immediately

Use Cases:
- Recipe viewing: User can interact with page, get timeout prompt, extend time
- Photo browsing: Continuous swiping prevents timeout
- Digital signage: No interaction = no prompt = smooth rotation
- MagicMirror modules: Single-finger swipes keep resetting timer

This provides the consistent UX requested where ANY user interaction
on ANY site enables the inactivity prompt logic.
