Feat(ui): add Turkish language support and UI enhancements
Introduces Turkish language support and several UI/UX improvements to the web management interface.
Refactor subtitle elements in accounts, dashboard, and models views to use styled badge containers with rounded backgrounds, borders, and improved typography for better visual consistency.
Add sorting functionality to the models table with clickable headers for columns like Stat, Model Identity, Global Quota, Next Reset, and Account Distribution. Includes dynamic sort icons and logic to handle ascending/descending order with appropriate defaults.

- Update description text to match current functionality
i18n:
