## Summary
* **What is the goal of this PR?**
* Fix the “Inverted” translation so reader orientation and color/filter
inversion can use separate labels.
* **What changes are included?**
* Adds `STR_ORIENTATION_INVERTED` for the inverted portrait orientation
option.
* Updates the reader orientation setting to use
`STR_ORIENTATION_INVERTED` instead of reusing `STR_INVERTED`.
* Leaves `STR_INVERTED` for the sleep cover filter and tilt page-turn
mode
* Adds the new orientation string across all 26 locale YAML files.
## Additional Context
* The original issue was found by a user in German, where `STR_INVERTED`
was translated as `Hochformat 180°`, which made sense for orientation
but not for color filters.
* This is a UI-label-only change. It does not change persisted
orientation values or settings behavior.
* Reviewer note: non-English wording may still benefit from
native-speaker review, especially for the new orientation-specific
labels and to verify the interchangeable usage between inverted color
and inverted tilt page turn direction.

## Summary
This PR enhances the EPUB reader's bookmark system with two
complementary improvements: a per-page bookmark indicator icon and
toggle behavior on the existing long-press action.
---
### What Changed
**Bookmark Toggle (was: add-only)**
The long-press Confirm action now toggles bookmarks rather than always
adding. `addBookmark()` checks whether a bookmark with the same xpath
already exists in the in-memory cache:
- If found → removes it and shows "Bookmark removed."
- If not found → adds it and shows "Bookmark added."
A new `STR_BOOKMARK_REMOVED` translation string was added to support the
removal message.
**Bookmark Icon Indicator**
A `BookmarkIcon` is now drawn at the top-right corner of the page
whenever the current page has a bookmark. `updateBookmarkFlag()` is
called at render time to determine whether the current page is
bookmarked.
**In-Memory Bookmark Cache**
Bookmarks are now loaded into `cachedBookmarks` on `onEnter()` rather
than being re-read from disk on every toggle. All subsequent add/remove
operations work against this cache and flush to disk, avoiding redundant
file reads on each bookmark action.
**Faster bookmarks list**
Previously, calculating "page X/Y" for each entry required decompressing
the entire spine item. We now persist `si`/`pc`/`pp` (spine index, page
count, and page progress) in the bookmark JSON when saving, and restore
them when loading. This avoids the expensive `toCrossPoint()` loop in
`onEnter()`, significantly reducing the cost of initializing the
bookmarks list.
---
### Files Changed
- `EpubReaderActivity.cpp` — `addBookmark()` toggle logic,
`updateBookmarkFlag()` (new), icon rendering in `renderContents()`,
cache initialization in `onEnter()`
- `EpubReaderActivity.h` — new fields: `currentPageBookmarked`,
`bookmarkRemoved`, `cachedBookmarks`; new method declaration
`updateBookmarkFlag()`

## Summary
* Adds a live font preview pane to the font selection screen so users
can see how a font looks before committing to it.
* Changes
* A preview pane occupying the top 30% of the font selection screen,
rendering sample pangram text in the previewed font
* A two-step confirm flow: first press (enter button) previews the font,
second press selects it
* Back restores the original font settings, so browsing has no side
effects
* Layout dimensions cached in `onEnter()` to avoid redundant
recalculation between `loop()` and `render()`
## Additional Context
* Preview sample text is hardcoded English; didn't want to use AI for
translation as I would not be able to verify the output in most
languages...
* The preview pane reduces visible list height; this is compensated by
passing the reserved height into `getNumberOfItemsPerPage`

## Summary
* **What is the goal of this PR?**
Mainly fixes#2196, but also allows users to set a sleep time of 1~30
min or to never sleep.
* **What changes are included?**
1. Revert changes from #1948 and #2137 (Sorry @Uri-Tauber)
2. Cherrypick changes from
https://github.com/uxjulia/CrossInk/commit/0cb91c3dd1c63f0559d4392fadc4a8340af5bdde
and
https://github.com/uxjulia/CrossInk/commit/4e6bd634b6ede51ff1a7107ba3e8efcd152bc6ee
for a timeout interval picker UI, the custom sleep time feature, and
migrate the existing setting in v1.3.0, `sleepTimeout`, to
`sleepTimeoutMinutes` (Thanks! @uxjulia)
3. Add a "Never" at the far right of the timeout interval picker
