3 bugs fixed:
1. T key theme path error (ERR_FILE_NOT_FOUND)
- cycleTheme now auto-detects theme base path from existing
<link id='theme-link'> href instead of hardcoding 'assets/themes/'
- Works correctly from any subdirectory depth (e.g. templates/full-decks/xxx/)
2. Presenter popup colors wrong (gray/missing styles)
- Popup <body> now inherits host page's body classes (e.g. .tpl-presenter-mode-reveal)
so scoped CSS selectors like .tpl-xxx .slide work correctly
- Popup <html> inherits all host attributes (lang, data-themes, data-theme, etc.)
- Added .pv-body class with !important overrides to ensure presenter layout
wins over any host CSS that might affect body
3. Presenter popup slide layout mismatch
- Slides are now wrapped in a proper <div class='deck'> container at
exactly 1920×1080px, matching the audience window's DOM structure
- .pv-stage-inner .deck .slide forced to 1920×1080 with !important
- Removed all manual style.xxx = overrides in renderSlide(); layout comes
purely from CSS now, matching the audience view pixel-for-pixel
- Hidden runtime chrome (.progress-bar, .notes-overlay, .overview, etc.)
