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.

# Expandable Selected Row for Long Filenames
## Task
Implement a mod enhancement to PR #1019 (Display file extensions in File Browser). When the selected row's filename is too long, expand that row to 2 lines with character-level text wrapping. The file extension moves to the bottom-right of the expanded area. Non-selected rows retain single-line truncation behavior.
## Changes Made
### `src/components/themes/BaseTheme.cpp`
- Added `wrapTextToLines` static helper in the anonymous namespace: character-level UTF-8-aware text wrapping with "..." truncation on the final line.
- Modified `drawList`: pre-loop expansion detection for the selected item, pagination adjustment (`pageItems - 1`), expanded selection highlight (`2 * rowHeight`), 2-line title rendering via `wrapTextToLines`, extension repositioned to bottom-right of expanded area, `yPos` tracking for subsequent items.
### `src/components/themes/lyra/LyraTheme.cpp`
- Added identical `wrapTextToLines` helper.
- Modified `drawList` with analogous expansion logic, adapted for Lyra-specific styling (rounded-rect selection highlight, icon support, scroll bar-aware content width, preliminary text width computation for expansion check).
### `mod/prs/MERGED.md`
- Updated PR #1019 section to document the mod enhancement, files modified, and design decisions.
## Follow-up Items
- Visual testing on device to verify text positioning and edge cases (very long single-word filenames, last item on page expanding, single-item lists).
- The page-up/page-down navigation in `MyLibraryActivity::loop()` uses the base `pageItems` from `getNumberOfItemsPerPage` which doesn't account for expansion. This causes a minor cosmetic mismatch (page jump size differs by 1 from visual page when expansion is active) but is functionally correct.
