Aim
Similar to T345251: [Non-MVP] Decide a lexical prefix for displaying in front of temporary usernames and T347209: Investigate: Grey background for temporary usernames in signatures, mentions etc, it would be useful to have expired temporary accounts appear differently. E.g. instead of ~2024-681 we might see ~2024-681 (expired) or ~2024-681 (disabled). That way, editors won't waste time pinging temp users or e.g. attempting to block temp user accounts that aren't in use anymore.
Design
If temp account has expired:
- Strikethrough temporary account name
- Use tooltip to display text on hover: Temporary account has expired
