Fixes (Sweep: hardcoded English labels and descriptions in Scheduled Sweep form (missing i18n))#1545

This PR replaces hardcoded English labels, descriptions, action buttons, and validation messages in the Scheduled Sweep form with proper i18n translation keys.

Changes

• i18n Keys: Added missing labels, descriptions, and validation feedback under the scheduler namespace in src/i18n/locales/en/translation.json.
• SweepForm: Replaced raw strings for includeMakerSessions, min/maxNumberOfCollaborators, minNumberOfTransactionsPerJar, roundingChanceInPercent, and validation errors with t('scheduler...').
• SweepDestinationInputs: Replaced hardcoded "Add additional destination" with t('scheduler.button_add_destination').
• Testing: Added unit test coverage in SweepPage.test.tsx verifying that all scheduler option labels and descriptions render properly, and updated SweepDestinationInputs.test.tsx.

Steps to Reproduce

1. Go to Settings (/settings) and switch the application language to Deutsch (German).
2. Navigate to Sweep (/sweep) and open the Scheduled Sweep options dropdown ("Optionen für geplanten Sweep").
3. Before: The options section header was translated, but all internal option labels, slider descriptions, and action buttons remained hardcoded in English.
4. After: All labels, helper texts, and buttons are dynamically translated to German according to the active locale.

Note: The screenshots below compare the Scheduled Sweep options with the language set to German (Deutsch).
