Adds bookmark functionality with persistent storage, quick menu for
in-reader actions, Search tab with character picker, and unified
tab bar navigation across all library tabs.
Includes:
- BookmarkStore and BookmarkListActivity for bookmark management
- QuickMenuActivity for in-reader quick actions
- Reader bookmark integration with visual indicators
- Enhanced tab bar with scrolling, overflow indicators, and cursor
- Search tab with character picker and result navigation
- Consistent tab bar navigation (Up from top enters tab bar mode)
Adds Search tab to MyLibraryActivity with character picker for building
search queries, result navigation with long press jump-to-end support,
and Bookmarks tab integration. Implements consistent tab bar navigation
across all tabs - pressing Up from top of any list enters tab bar mode
with visible cursor indicators, Left/Right switches tabs, Down enters
list at top, and Up jumps to bottom of list.
Tab bar now scrolls to keep selected tab visible when content overflows.
Adds triangle overflow indicators and optional bullet cursor indicators
around the active tab for visual focus feedback.

Cherry-picked from upstream PR #404 with conflict resolution:
- Replaced flaky TCP-based Calibre wireless with WebSocket-based transfer
- Added OPDS authentication support (username/password in settings)
- Renamed "Calibre Library" to "OPDS Browser" in home menu
- Added UDP discovery for Calibre plugin communication
- Merged user's custom settings (customFontIndex, fallbackFontFamily, pinnedListName)
- Applied vTaskDelay cleanup after task deletion
- Kept existing "Calibre Settings" menu item (skipped KOReader Sync per preference)
Fixes issue #334 (Calibre wireless transfer not working)
Manual implementation of upstream PR #525
Added flushPartWordBuffer() function and call it before <br/> handling
to fix issue where preceding word was incorrectly wrapped to new line
- Add /api/hash endpoint to compute and cache MD5 hashes on demand
- Extend /api/files response with md5 field for EPUBs (null if not cached)
- Compute and cache MD5 automatically after EPUB uploads
- Add flush() before close() in WebSocket and HTTP upload handlers
- New Md5Utils module using ESP32's mbedtls for chunked hash computation
The MD5 hashes enable the companion app to detect file changes without
downloading content. Hashes are cached in each book's .crosspoint cache
directory and invalidated when file size changes.
