cottongin dfbc931c14 mod: Phase 1 - bring forward mod-exclusive files with ActivityManager migration
Brings ~55 mod-exclusive files to the upstream-based mod/master-resync branch:

Activities (migrated to new ActivityManager pattern):
- Clock/Time: SetTimeActivity, SetTimezoneOffsetActivity, NtpSyncActivity
- Dictionary: DictionaryDefinitionActivity, DictionarySuggestionsActivity,
  DictionaryWordSelectActivity, LookedUpWordsActivity
- Bookmark: EpubReaderBookmarkSelectionActivity
- Book management: BookManageMenuActivity, EndOfBookMenuActivity
- OPDS: OpdsServerListActivity, OpdsSettingsActivity
- Utility: DirectoryPickerActivity, NumericStepperActivity

Utilities (unchanged):
- BookManager, BookSettings, BookmarkStore, BootNtpSync
- Dictionary, LookupHistory, TimeSync, OpdsServerStore

Libraries: PlaceholderCover, TableData, ChapterXPathIndexer
Scripts: inject_mod_version, generate_book_icon, preview_placeholder_cover
Docs: KOReader sync XPath mapping

Migration changes:
- ActivityWithSubactivity -> Activity base class
- Callback constructors -> finish()/setResult() pattern
- enterNewActivity() -> startActivityForResult()
- Activity::RenderLock&& -> RenderLock&&

These files won't compile yet - they reference mod settings and I18n
strings that will be added in subsequent phases.

# Implement BmpViewer Activity (upstream PR #887)
## Task
Port the BmpViewer feature from upstream crosspoint-reader PR #887 to the mod/master fork, enabling .bmp file viewing from the file browser.
## Changes Made
### New Files
- **src/activities/util/BmpViewerActivity.h** -- Activity subclass declaration with file path, onGoBack callback, and loadFailed state
- **src/activities/util/BmpViewerActivity.cpp** -- BMP loading/rendering implementation: shows loading indicator, opens file via Storage HAL, parses BMP headers, computes centered position with aspect-ratio-preserving layout, renders via `renderer.drawBitmap()`, draws localized back button hint, handles back button input in loop
### Modified Files
- **src/activities/reader/ReaderActivity.h** -- Added `isBmpFile()` and `onGoToBmpViewer()` private declarations
- **src/activities/reader/ReaderActivity.cpp** -- Added BmpViewerActivity include, `isBmpFile()` implementation, `onGoToBmpViewer()` implementation (sets currentBookPath, exits, enters BmpViewerActivity with goToLibrary callback), BMP routing in `onEnter()` before XTC/TXT checks
- **src/activities/home/MyLibraryActivity.cpp** -- Added `.bmp` to the file extension filter in `loadFiles()`
- **src/components/themes/lyra/LyraTheme.cpp** -- Changed `fillRect` to `fillRoundedRect` in `drawButtonHints()` for both FULL and SMALL button sizes to prevent white rectangles overflowing rounded button borders
## Build Result
- PlatformIO build SUCCESS (default env)
- RAM: 32.7% (107,308 / 327,680 bytes)
- Flash: 71.1% (4,657,244 / 6,553,600 bytes)
## Follow-up Items
- Test on hardware with various BMP files (different sizes, bit depths)
- Consider adding image scaling for oversized BMPs (currently `drawBitmap` handles scaling)
- Future enhancements mentioned in upstream PR: next/prev image navigation, "display and sleep" button
