Replace 13 per-accessor static std::string blank locals with a single
file-scope kBlank (~384 bytes DRAM saved). Add Epub::getMetadata()
returning the full BookMetadata struct. Refactor buildLayout from 14
individual parameters to a single BookMetadata const ref + fileSize.

Add parsing for dc:publisher, dc:date, dc:subject, dc:rights,
dc:contributor, dc:identifier (prefers ISBN scheme), and
calibre:rating. All new fields serialized in BookMetadataCache
(version bumped to 7) and displayed in BookInfoActivity with
rating shown as N/5 scale.

When BookInfo is opened for a book with no existing cache,
epub.load(true, true) triggers a 1-2s full parse. Show a
"Loading..." popup with progress bar so the device doesn't
appear frozen. Popup only appears on the fallback path —
cached books load silently. Same pattern for XTC books.

- Fix BookInfo buttons: Left/Right front = scroll down/up, Confirm = no-op,
side buttons retained. Separate Up/Down hints on btn3/btn4.
- Fallback load: try epub.load(true, true) when cache-only load fails,
so Book Info works for unopened books.
- Add "Book Info" to ManageBook menu (BOOK_INFO action) with handlers in
all 4 result sites (Home, Recent, FileBrowser, Reader).
- Fix HomeActivity cover regen: call generateCoverBmp(false) + validate
with isValidThumbnailBmp before falling to placeholder, matching the
reader's multi-tier fallback pipeline. Same for XTC branch.

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.
