M3: restore last view settings when reopening documents (#1767)

A file opened again shows the page, zoom and page display it was last shown with, as Acrobat's "Restore last view settings when reopening documents" does: remembered by path (the last 100 files) when its tab closes or settings are saved with it open, applied over the file's own initial view, on by default and switched off in Preferences ▸ Documents and view.

 - **2026-10-15 (community, M14, Polish signature panel):** A Polish signature panel listed its details in English: the catalog lacked every signature wording, the changes after signing they name and 34 UI literals. All 101 are translated; `polish_covers_ui_literals` and `polish_says_what_a_signature_says` keep them so. Estimates unchanged.
 - **2026-10-14 (M14, Finnish localization):** Added Finnish as another interface and date language, with a 2,674-entry catalog covering every key of the other bundled catalogs and two-form plurals (partitive after numbers other than 1). Calendar dates use partitive month names (`14. lokakuuta 2026`). Coverage tests check commands/tools, scanned UI literals and bundled catalog keys. AI-assisted; native proofreading pending.
 - **2026-10-14 (M14, Catalan localization):** Added Catalan as another interface and date language, with a 2,592-entry clean-room catalog, one/other plurals and coverage tests for commands, tools, UI literals and every key in the other catalogs. A native Catalan speaker (the contributor) has reviewed the translation. Estimates unchanged.
+
+- **2026-10-15 (M3, #1767):** Restore last view settings when reopening documents, as Acrobat's preference does: a file opened again shows the page, zoom and page display it was last shown with (remembered for the last 100 files when a tab closes or settings are saved), over the file's own initial view; on by default, Preferences ▸ Documents and view turns it off.
 - **2026-10-13 (M3, native-opening candidate):** Chosen tools survive preparation, conversion and password retries; startup intake waits for pending preparation. Regression tests cover completion, cancellation and document identity. Estimates unchanged.
 - **2026-10-13 (community, M3, #531 touchpad momentum):** On Wayland a two-finger swipe keeps gliding after the fingers lift and slows to a stop, measured from the gesture's last 0.1 s and decaying with a 0.35 s time constant through the #759 1:1 path. Any wheel input, click, key, zoom or edge ends it (fingers resting on the touchpad don't yet: the vendored winit binds no Wayland hold gestures); single-page paging, macOS (which sends its own momentum), the web, and Animation effects Off never glide. Unit tests for the physics and two headless view tests. Estimates unchanged.
 - **2026-10-13 (M3, native-open admission):** Later prepared replies stay queued while a modal or native picker owns the foreground. Picker completion, cancellation and abandonment wake retained opens. Regressions cover recipient ownership, exactly-once admission, source/history preservation and one-shot repaint requests. Estimates unchanged.
