Lataa KillerPDF 1.8.5

1.8.5 improves saving, signatures, installation, and keyboard controls, and adds optional startup update checks.

### Fixed

- Completed remaining dialog and installer translations and refreshed the website guides.
- Moved the keyboard shortcut toggle to the footer beside the online guide.
- Evenly spaced About options, moved startup update checks to the bottom, and aligned Clear all Data with the top row.
- Corrected WinGet release manifests to run the installer and include the required desktop runtime (#386).
- Kept scroll and manual zoom settings independent between document tabs and restored them when reopening files (#399).
- Kept selected-page transforms when retained pages contain inconsistent font-width metadata.
- Standalone uninstall dialogs use the default Dark/Green theme, and installation errors use themed dialogs.
- Localized the document page count and Italian certificate label, and included the add-bookmark row when sizing the sidebar (#394).
- Used the destination monitor when calculating maximized client bounds during a cross-monitor move (#363).
- Refreshed legacy PDF file associations to open the installed app instead of the installer (#393).
- Corrected Italian translations (#395). (Thanks @bovirus)
- Restored saving markup to tagged PDFs while preserving their structure, and finished markup processing before overwriting the destination.

### Added

- Added startup update checks, enabled by default, with confirmation before updating and a shared toggle in About and the update dialog.
- Added Ctrl+R and Ctrl+Shift+R to rotate selected pages clockwise and counterclockwise.
- Added a keyboard shortcut toggle with an always-available Ctrl+Shift+K recovery chord (#405).
- Added page size selection with current-page, Letter, A4, Legal, and custom dimensions when inserting blank pages (#400).
- Added Open Containing Folder to document tab menus (#399).
- Added a `--batch-render` command that renders pages of a file or tree to PNG with a per-page timing log.
