v1.0.7: Fix false offline modifications causing 'untitled' pages

Root cause chain:
1. JS _pendingSet cleared prematurely in onReady (0ms), letting onChange
   fire during initial content load and set userEdited=true
2. onAutoSave didn't check isEditorReadOnly, firing even for read-only pages
3. Markdown round-trip (extractText → markdownToBlocks → blocksToMarkdown)
   produced different output, triggering false change detection
4. onSaveContent passed null for title when no title changes, which
   CachedApi converted to empty string, causing server to set title to 'untitled'

Fixes:
- JS: Remove premature _pendingSet clearing in onReady; increase timeout to 500ms
- Kotlin: onAutoSave checks isEditorReadOnly (no auto-save in read-only mode)
- Kotlin: Save operations always pass current title (never null) to prevent
  empty title being sent to server
- Kotlin: Add isContentLoading flag to suppress onContentChanged during initial
  content load, preventing false currentPageContent updates
- Added APK versioned naming for Obtanium compatibility
