[Client/Server] Keep non-deck files out of the deck storage (#7352)

The local deck and replay browsers list every file in the folder, so a
stray file (e.g. a PNG screenshot of a deck) can be parsed as a garbage
plaintext deck, opened in the editor, and uploaded. The server also
accepts oversized deck payloads with only silent truncation.

Hide files that are not in a supported deck/replay format in the two
QFileSystemModel views (directories stay visible), skip them when opening,
reject them when uploading, and make the server reject deck uploads larger
than MAX_FILE_LENGTH instead of truncating them.
