fix: several bookmarks UX improvments (#2372)

## 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()`

---
