Update translations and add trial eligibility in plan picker

Added translations in "plan-picker" for better localization support. Introduced a new functionality to check trial eligibility where existing customers can't start a trial. Removed unnecessary billing line items like 'per-seat' and 'metered'. Also, made significant changes in multiple files to align with the updated internationalization best practices. The changes aim to make application more user-friendly across different locales and provide accurate trial period conditions.
