Settings reorganized, plus Home and name updates

Settings

• Settings now has its own left menu, with Account and Security, Data updates, AI integration, Display and more opening by category.
• SNS accounts, subscription, plans, referrals, team and data import also share the settings menu and a "Back to settings" link.
• When loading fails, it is distinguished from "no subscription" or an empty list, and you can retry on the spot. Unsaved input is confirmed before you leave.
• In "Display" you can choose the language, time zone (searchable by city name), 12/24-hour format and the first day of the week.

Home

• Choose which accounts to show and check scheduled posts, saved comments and drafts together. All accounts are shown at first, and any you uncheck are remembered.
• The upcoming posts and recent comments panels are now the same height, and comments show the author's icon.

Other changes

• The official name is unified as Ritomira. You can also find us by searching "リトミラ" or "りとみら".
• A new-login notification is no longer sent for sign-ins from a browser you have used before. Sign-ins from a new browser or another device are still notified.
• We improved security, including preventing an in-progress login from being used twice, stricter checks of payment return URLs, and a review of file storage and AI integration entry points.
• The achievements (badges) feature in the activity history has ended.
