feat: improve export functionality and fix configuration issues

- Add custom export directory selection in GUI export dialog
- Change default export directory from ~/.local/state/totalrecall to ~/Downloads
- Remove broken voice configuration from config file (voice is always random)
- Fix discrepancies between code defaults and example config
- Remove unimplemented image cache settings from example config

The voice configuration was not working due to a bug where it only read from config if
the command-line flag was set to "nova" (but default was empty string). Since voices
are randomly selected anyway, this configuration option has been removed.
