Ports upstream PR #1342 (feat: Add Book Info screen, richer metadata,
and safer file-browser controls) with mod-specific adaptations:
- Parse and cache series, seriesIndex, description from EPUB OPF
- Bump book.bin cache version to 6 for new metadata fields
- Add BookInfoActivity (new screen) accessible via Right button in FileBrowser
- Add ManageBook menu via Left button in FileBrowser (replaces upstream hidden delete)
- Guard all delete/archive actions with ConfirmationActivity (10 call sites)
- Add inputArmed gating to ConfirmationActivity to prevent accidental confirmation
- Safe deserialization: readString now returns bool with MAX_STRING_LENGTH guard
- Add series field to RecentBooksStore with JSON and binary serialization
- Add i18n keys: STR_BOOK_INFO, STR_AUTHOR, STR_SERIES, STR_FILE_SIZE, etc.
Made-with: Cursor
Re-add DynamicEnum entries for preferredPortrait/preferredLandscape in
Settings with JSON persistence. Restore long-press Confirm on the
reader menu's orientation toggle to open an inline sub-menu with all
4 orientation options.

## Summary
* **What is the goal of this PR?** Eliminate the 3-file / 4-location
overhead for adding a new setting. Previously, every new setting
required manually editing JsonSettingsIO.cpp in two places (save +
load), duplicating knowledge already present in SettingsList.h. After
this PR, JsonSettingsIO.cpp never needs to be touched again for standard
settings.
* **What changes are included?**
* `SettingInfo` (in `SettingsActivity.h`) gains one new field: `bool
obfuscated` (base64 save/load for passwords), with a fluent builder
method `.withObfuscated()`. The previously proposed
`defaultValue`/`withDefault()` approach was dropped in favour of reading
the struct field's own initializer value as the fallback (see below).
* `SettingsList.h` entries are annotated with `.withObfuscated()` on the
OPDS password entry. The list is now returned as a `static const`
singleton (`const std::vector<SettingInfo>&`), so it is constructed
exactly once. A missing `key`/`category` on the
`statusBarProgressBarThickness` entry was also fixed — it was previously
skipped by the generic save loop, so changes were silently lost on
restart.
* `JsonSettingsIO::saveSettings` and `loadSettings` replace their ~90
lines of manual per-field code with a single generic loop over
`getSettingsList()`. The loop uses `info.key`,
`info.valuePtr`/`info.stringOffset`+`info.stringMaxLen` (for char-array
string fields), `info.enumValues.size()` (for enum clamping), and
`info.obfuscated`.
* **Default values**: instead of a duplicated `defaultValue` field in
`SettingInfo`, `loadSettings` reads `s.*(info.valuePtr)` *before*
overwriting it. Because `CrossPointSettings` is default-constructed
before `loadSettings` is called, this captures each field's struct
initializer value as the JSON-absent fallback. The single source of
truth for defaults is `CrossPointSettings.h`.
* One post-loop special case remains explicitly: the four `frontButton*`
remap fields (managed by the RemapFrontButtons sub-activity, not in
SettingsList) and `validateFrontButtonMapping()`.
* One pre-loop migration guard handles legacy settings files that
predate the status bar refactor: if `statusBarChapterPageCount` is
absent from the JSON, `applyLegacyStatusBarSettings()` is called first
so the generic loop picks up the migrated values as defaults and applies
its normal clamping.
* OPDS password backward-compat migration (plain `opdsPassword` →
obfuscated `opdsPassword_obf`) is preserved inside the generic
obfuscated-string path.
## Additional Context
Say we want to add a new `bookmarkStyle` enum setting with options
`DOT`, `LINE`, `NONE` and a default of `DOT`:
1. `src/CrossPointSettings.h` — add enum and member:
```cpp
enum BOOKMARK_STYLE { BOOKMARK_DOT = 0, BOOKMARK_LINE = 1, BOOKMARK_NONE = 2 };
uint8_t bookmarkStyle = BOOKMARK_DOT;
```
2. `lib/I18n/translations/english.yaml` — add display strings:
```yaml
STR_BOOKMARK_STYLE: "Bookmark Style"
STR_BOOKMARK_DOT: "Dot"
STR_BOOKMARK_LINE: "Line"
```
(Other language files will fall back to English if not translated. Run
`gen_i18n.py` to regenerate `I18nKeys.h`.)
3. `src/SettingsList.h` — add one entry in the appropriate category:
```cpp
SettingInfo::Enum(StrId::STR_BOOKMARK_STYLE, &CrossPointSettings::bookmarkStyle,
{StrId::STR_BOOKMARK_DOT, StrId::STR_BOOKMARK_LINE, StrId::STR_NONE_OPT},
"bookmarkStyle", StrId::STR_CAT_READER),
```
That's it — no default annotation needed anywhere, because
`bookmarkStyle = BOOKMARK_DOT` in the struct already provides the
fallback. The setting will automatically persist to JSON on save, load
with clamping on boot, appear in the device settings UI under the Reader
category, and be exposed via the web API — all with no further changes.

## Summary
This PR aims to reduce the complexity of the status bar by splitting the
setting into 5:
- Chapter Page Count
- Book Progress %
- Progress Bar
- Chapter Title
- Battery Indicator
These are located within the new StausBarSettings activity, which also
shows a preview of the bar the user has created

/>
When updating from a previous version, the user's past settings are
honoured.
## Additional Context
The PR aims to remove any duplication of status bar code where possible,
and extracts the status bar rendering into a new component - StatusBar
It also adds a new (optional) padding option to the progress bar to
allow the status bar to be shifted upwards - this is only intended for
use in the settings.

## Summary
* This PR introduces a migration from binary file storage to JSON-based
storage for application settings, state, and various credential stores.
This improves readability, maintainability, and allows for easier manual
configuration editing.
* Benefits:
- Settings files are now JSON and can be easily read/edited manually
- Easier to inspect application state and settings during development
- JSON structure is more flexible for future changes
* Drawback: around 15k of additional flash usage
* Compatibility: Seamless migration preserves existing user data
## Additional Context
1. New JSON I/O Infrastructure files:
- JsonSettingsIO: Core JSON serialization/deserialization logic using
ArduinoJson library
- ObfuscationUtils: XOR-based password obfuscation for sensitive data
2. Migrated Components (now use JSON storage with automatic binary
migration):
- CrossPointSettings (settings.json): Main application settings
- CrossPointState (state.json): Application state (open book, sleep
mode, etc.)
- WifiCredentialStore (wifi.json): WiFi network credentials (Password
Obfuscation: Sensitive data like WiFi passwords, uses XOR encryption
with fixed keys. Note: This is obfuscation, not cryptographic security -
passwords can be recovered with the key)
- KOReaderCredentialStore (koreader.json): KOReader sync credentials
- RecentBooksStore (recent.json): Recently opened books list
3. Migration Logic
- Forward Compatibility: New installations use JSON format
- Backward Compatibility: Existing binary files are automatically
migrated to JSON on first load
- Backup Safety: Original binary files are renamed with .bak extension
after successful migration
- Fallback Handling: If JSON parsing fails, system falls back to binary
loading
4. Infrastructure Updates
- HalStorage: Added rename() method for backup operations
