Die max()-Semantik aus v14 verglich nur die grobe scroll_fraction. Da
scroll_fraction und position_anchor gemeinsam, aber entkoppelt gespeichert
werden, konnte ein einzelner Save mit transient zu hoher fraction (z.B.
instabiles Layout beim Laden) die Position dauerhaft einfrieren: jeder
spätere echte Fortschritt hatte eine kleinere fraction und wurde inklusive
Anker verworfen — der Leser landete immer wieder an derselben Stelle.
Fix: Vergleich läuft jetzt über den Blockindex im Anker (die Größe, die
auch die Sprungposition bestimmt), mit innerFraction als Tiebreaker.
scroll_fraction dient nur noch als Fallback für PDFs ohne Anker. Server
(_progress_is_further) und Client (_cmpProgress) nutzen identische Logik;
loadBookList-Push und lokaler Cache ebenfalls. Bestehende eingefrorene
Einträge entfrieren sich beim ersten Weiterlesen selbst.

Der am weitesten gelesene Wert hat immer Vorrang:
- Server: scroll_fraction = max(neu, aktuell) — ein afk-Fenster bei 10%
kann nicht mehr 80% überschreiben
- Client loadBookList: wenn lokaler Fortschritt > Server, wird gepusht
und für die Anzeige verwendet (deckt Offline-Lesen ab)
- Pending-Flag-Logik entfernt — nicht mehr nötig dank max-Semantik
- saveReaderProgress(force=true): neuer force-Parameter schreibt
Position unabhängig vom gespeicherten Maximum; Button ⚑ im
Reader-Header für den Ausnahmefall "zurück-zum-Anfang"

replace-data endpoint now optionally accepts meta_ct/meta_iv.
The client extracts title/author from the uploaded file (same as
normal upload), re-encrypts metadata with the current key, and sends
both data and meta together — so broken books are fully restored
including their displayed title and author.

When a book fails to open, a '!' button appears next to it in the list.
Clicking it prompts for the original file; the file is re-encrypted with
the current key and replaces the broken ciphertext on the server while
keeping all metadata, progress, highlights and bookmarks intact.
- Add POST /books/<pk>/replace-data/ endpoint (updates data only)
- Add _evictCachedBook() to clear IndexedDB cache for a single book
- Replace complex client-side re-encryption on password change with a
simple confirm() warning that books will need to be re-uploaded

The encryption key is PBKDF2-derived from the login password. Changing
the password without migrating the key would make all books undecryptable
on the next login.
- Add POST /books/<pk>/rekey/ endpoint to replace a book's ciphertexts
- Password change form is now JS-driven: before submitting to the server,
derives the old key, verifies it matches localStorage, derives the new
key, re-encrypts all books (data + meta) and their highlights/bookmarks,
updates localStorage, then submits the Django form

- HIGHLIGHTS_MAX_BYTES, BOOKMARKS_MAX_BYTES: books size limits now in settings
- PODCAST_INBOX_PAGE_SIZE: shared between podcasts/views.py and app.js via DIORA_CONFIG
- VOLUME_DEFAULT: radio stream player default volume
- ITUNES_TIMEOUT: unified iTunes API timeout (was 5s vs 6s inconsistency)

- Create EBookProgress on upload so new books get a last_read timestamp
and sort to the top of the book list
- Update frontend file size check from 10 MB to 50 MB
- Fix backend error message to say 50 MB instead of 10 MB

Replaces scroll_fraction-only position tracking with element-based
anchors ("{index}:{innerFraction}"). Position is now stable across
font size changes and different screen sizes. A ResizeObserver
restores the anchor on viewport/orientation changes.
Falls back to scroll_fraction for books without a saved anchor.

Backend includes last_read from EBookProgress.updated_at.
Frontend sorts by last_read desc, unread books by uploaded_at desc.
