Fix whitespace stripping in common date/location templates

- Compute common_date and common_location inline using {%- set -%} syntax
  instead of as separate HA variables, which strips leading whitespace
- Fix CASE 3 (Changed) handler missing common_date/common_location support
- Remove unused global common_date and common_location variable definitions
- Apply fix to all message templates: scheduled assets (per_album, combined),
  realtime notifications (assets_added, changed), and Telegram messages
