Use XDG/Flatpak standard directories for data storage

- Update history_manager to use GLib.get_user_config_dir()
- Update project_manager to use GLib.get_user_data_dir()
- Remove old filesystem permission from Flatpak manifest
- Fix Flatpak manifest: runtime version 49→47, correct git source URL

Data now stored in:
- Flatpak: ~/.var/app/cz.vesp.roster/{config,data}/cz.vesp.roster/
- Native: ~/.{config,local/share}/cz.vesp.roster/

cz.vesp.roster.json
