- Fix ignored return value in TxtReaderActivity
- Remove unused variables across multiple files
- Add const correctness to DictionaryMargins and EpubReaderActivity
- Replace inefficient substr patterns with resize+append

- Add cppcheck suppression for ValueFlow analysis limitation
Resolves all low, medium, and high severity cppcheck defects.
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)
- 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.
Merges progress bar status bar feature from merge-438:
- Added FULL_WITH_PROGRESS_BAR and ONLY_PROGRESS_BAR status bar modes

Preserves features from current branch:
- Content offset tracking for position restoration (EPUB_PROGRESS_VERSION)
- drawBatteryLarge() function
- Sleep Screen Cover Mode "Actual" option
Adds full support for book lists managed by the Companion App:
- New /list API endpoints (GET/POST) for uploading, retrieving, and deleting lists
- BookListStore for binary serialization of lists to /.lists/ directory
- ListViewActivity for viewing list contents with book thumbnails
- Reading Lists tab in My Library with pin/unpin and delete actions
- Pinnable list shortcut on home screen (split button layout)
- Automatic cleanup of pinned status when lists are deleted
Integrates upstream PR #511 changes while preserving local delete/archive
functionality. Key changes:
- Add RecentBook struct with path, title, author fields
- Update RecentBooksStore to store and serialize metadata
- Implement version migration for existing recent.bin files
- Update MyLibraryActivity to display two-line items (title + author)
- Update EpubReaderActivity and XtcReaderActivity to pass metadata
Maintains backwards compatibility with delete/archive feature from
local commit d5a9873.
