Refactor card badge and multiselect template tags to properly implement and/or improve caching and context handling

- Updated `card_badge` and `card_multiselect` template tags to utilize `reverse_lazy` for URL resolution.
- Enhanced caching mechanisms in `card_badge.html` and `card_multiselect.html` to improve performance.
- Introduced a new template `_card_multiselect_options.html` for rendering multiselect options.
- Improved context management in `card_multiselect` to handle selected cards and dynamic placeholders.
- Added error handling for query hashing in `card_multiselect` to ensure robustness.
- Updated `trade_offer_tags` to optimize database queries using `select_related` for related objects.
