Fix clock persistence bug caused by stale legacy read in settings
deserialization. Add clock size setting (Small/Medium/Large) and
timezone selection with North American presets plus custom UTC offset.
Move all clock-related settings into a dedicated Clock tab, rename
"Home Screen Clock" to "Clock", and move minute-change detection to
main loop so the header clock updates on every screen.

- 1-book view: horizontal layout with cover left, title/author right
- 2-3 book view: fix cover stretching by preserving aspect ratio
- 0-book view: show "Choose something to read" placeholder
- Selection highlight now fully contains title and author text
- Add optional clock display in home screen header (AM/PM or 24H)
- Add "Home Screen Clock" setting under Display
- Add "Set Time" activity for manual clock setting via Settings
- Increase homeCoverTileHeight to 310 for title/author breathing room

Consolidate dictionary items: remove "Lookup Word History" and
"Delete Dictionary Cache" from the menu. Long-press on "Lookup Word"
opens history; delete-dict-cache is now a sentinel entry at the bottom
of the history list.
Replace "Reading Orientation" with "Toggle Portrait/Landscape" that
toggles between two configurable preferred orientations (new settings:
Preferred Portrait, Preferred Landscape). Long-press opens a manual
4-option orientation sub-menu.
Add "Toggle Font Size" menu item that cycles through font sizes and
applies on menu exit (with section re-layout).
Rename "Letterbox Fill" to "Override Letterbox Fill" and
"Sync Progress" to "Sync Reading Progress" in reader menu.
All long-press flows use ignoreNextConfirmRelease to prevent the
button release from triggering actions on the subsequent screen.

**What is the goal of this PR?**
This PR introduces Internationalization (i18n) support, enabling users
to switch the UI language dynamically.
**What changes are included?**
- Core Logic: Added I18n class (`lib/I18n/I18n.h/cpp`) to manage
language state and string retrieval.
- Data Structures:
- `lib/I18n/I18nStrings.h/cpp`: Static string arrays for each supported
language.
- `lib/I18n/I18nKeys.h`: Enum definitions for type-safe string access.
- `lib/I18n/translations.csv`: single source of truth.
- Documentation: Added `docs/i18n.md` detailing the workflow for
developers and translators.
- New Settings activity:
`src/activities/settings/LanguageSelectActivity.h/cpp`
This implementation (building on concepts from #505) prioritizes
performance and memory efficiency.
The core approach is to store all localized strings for each language in
dedicated arrays and access them via enums. This provides O(1) access
with zero runtime overhead, and avoids the heap allocations, hashing,
and collision handling required by `std::map` or `std::unordered_map`.
The main trade-off is that enums and string arrays must remain perfectly
synchronized—any mismatch would result in incorrect strings being
displayed in the UI.
To eliminate this risk, I added a Python script that automatically
generates `I18nStrings.h/.cpp` and `I18nKeys.h` from a CSV file, which
will serve as the single source of truth for all translations. The full
design and workflow are documented in `docs/i18n.md`.
- [x] Python script `generate_i18n.py` to auto-generate C++ files from
CSV
- [x] Populate translations.csv with initial translations.
Currently available translations: English, Español, Français, Deutsch,
Čeština, Português (Brasil), Русский, Svenska.
Thanks, community!
**Status:** EDIT: ready to be merged.
As a proof of concept, the SPANISH strings currently mirror the English
ones, but are fully uppercased.

Did you use AI tools to help write this code? _**< PARTIALLY >**_
I used AI for the black work of replacing strings with I18n references
across the project, and for generating the documentation. EDIT: also
some help with merging changes from master.
