feat(scanner): store EPUB reading direction at scan time

Fixed-layout EPUBs lean on the reading_direction column (the web reader
forces book.dir = rtl from it when the file didn't set direction
itself), but the scanner never populated it for EPUBs - only ComicInfo
fed it. Meanwhile real Japanese EPUBs declare page-progression-direction
on the OPF spine, which foliate reads client-side but nothing stored.

Read the spine attribute in the structured OPF parser and map it into
ReadingDirection in parseOPFContent (EPUB2/3, case-insensitive, plus
'right-to-left'/'left-to-right' spellings); undeclared stays empty
rather than forcing ltr, preserving the editor's Auto default. Sidecar
OPFs are metadata-only documents without spines, so the Calibre path is
a no-op. The merge gap-fill copies an embedded-only direction into a
blank sidecar field, and hand-set values keep winning through the
existing OverrideReadingDirection protection.

Tests: declared rtl/RTL/ltr, undeclared and unknown values staying
empty, plus sidecar-wins vs embedded-fills merge cases. Existing manga
EPUBs declaring rtl (verified live in-library) pick the value up on
their next scan, feeding the API and reader config mobile clients
consume.
