feat: add i18n support for team management UI and role table header (#3702)

# Description of Changes

- Replaced hardcoded strings in `team-details.html` and `teams.html`
with internationalized message tags (e.g., `team.members`, `team.role`,
etc.)
- Introduced new message keys for team management across multiple
`messages_*.properties` files
- Added `text-overflow` styling to a shared CSS file
(`modern-tables.css`) for reuse across admin pages
- Removed the unused `adminUserSettings.roles` translation key and
replaced it with the singular `adminUserSettings.role` where necessary

These changes improve internationalization coverage in the team
management views and prevent layout issues in tight table columns
through shared styling.

@Frooodle merge after #3701
