Replaced the `i18n` and `toml` dependencies with Fyne's built-in language system for localization management. Updated the `Localizer` implementation to handle translations using JSON files and embed functionality. Simplified language selection and persisted settings via Fyne's preferences API.
Added new dependencies and license details to both `menu/view.go` and `LICENSE-3RD-PARTY.txt`. Updated copyright notices, hyperlinks, and license text to reflect the latest projects and comply with their licensing terms.
