fix: Add encoding parameter to rclone S3 config to prevent filename quoting

Files with spaces like 'Hello World.md' were being displayed with single
quotes as ''Hello World.md'' on the server due to rclone's default S3
encoding behavior.

This fix adds 'encoding = Slash,InvalidUtf8' to the rclone configuration,
which tells rclone to only encode slashes and invalid UTF-8, not spaces
or other common filename characters.

Fixes #406
