Version 3.2.1

A bug-fix release for the JavaFX GUI, with two fixes contributed by the community. Thanks to Ladislav Nemec and Milos Jakubicek.

• Output suffix no longer piles up when switching presets — loading a preset with a different output suffix used to append it to the previous one (document_EM.pdf became document_EM_DL.pdf instead of document_DL.pdf). A derived output name is now recomputed with the new suffix, a name you typed yourself is kept, and a new session no longer starts with the output file name left over from the last run. See pull request 505.
• Proxy port is saved even without pressing Enter — a port typed into the TSA / Validation settings was only committed on Enter, so the DSS engine could quietly connect to the proxy on port 80. The field now commits on focus loss too, and out-of-range values are rejected. See pull request 512.
• Unconfirmed field edits are no longer lost — signing or timestamping via a keyboard shortcut, closing the window, and saving or loading a preset now pick up the proxy port and font size fields as shown on screen. File > Exit (Ctrl+Q) now saves the signing options, as closing the window already did.
• Linux Flatpak bundle on the GitHub release — it is now built from the same manifest as the Flathub one, so smartcard and YubiKey signing work there too.
• Dependency updates — BouncyCastle 1.86 and other routine library bumps.
