Keep KOSync limited to position synchronization and rely on measured page timings from the BookOrbit plugin for KOReader reading sessions. Remove legacy estimates at startup and rebuild affected daily totals.
Fixes#1233
Treat partial-hash matches across distinct books as unresolved so progress cannot be written to an unrelated file. Preserve same-book duplicates and user-scoped manual links as valid disambiguation paths.
Fixes#1135
KOReader reports a paged document's position as a page number and a reflowable one's as an
xpointer, but applySharedProgress treated every incoming position as an xpointer and
upsertReadingProgress hardcoded pageNumber to null on every write. A PDF synced from a device
therefore stored a correct percentage with no page, and the web reader reopened it at page 1.
The same write also destroyed a page the web reader had saved earlier, including during an
unattended bulk sweep, so this lost positions that were never synced from a device at all.
Carry the book file's format through hash resolution and pick the column from it. CBZ/CBR were
affected identically at the data level but masked in the UI, because the comic reader estimates
a page from the percentage when none is stored.
