feat: human-readable date format with timezone awareness

- Add format_due_date() function that formats dates as '4 April 2026'
  or '4 April 2026 14:30 (Asia/Jakarta)' with timezone support
- Update format_bounty() to use timezone-aware date formatting
- Update cmd_bounty, cmd_my, cmd_add to pass room_id for timezone
- Dates now display in room's configured timezone
- Fixes #54
