[conflict_resolver] Add description field

[charlottesce]

Brief summary of changes

This adds a 'Description' field to the Conflict Resolver module (both Resolved and Unresolved tabs), which corresponds to the description of the 'Question' with the conflict. Instead of using parameter_type like in the CCNA code, it uses /dictionary/module/instruments to get the description of the fields. Since some fields don't have descriptions (e.g. some _status variables), the empty string is used as default.

Changes have been made to the Instrument_LINST file such that numeric and date elements are added to the dictionary, even if they are not in the top page (inspired by the change in #8869).

Testing instructions (if applicable)

1. Go to Clinical -> Conflict Resolver
2. Ensure both tabs 'Unresolved' and 'Resolved' load correctly, and in both, ensure that:
   a. You can see a 'Description' selection filter and the field in the table with conflicts
   b. You can input some value in the 'Description' selection filter (e.g. 'date') and that conflicts are filtered appropriately
3. Make sure the rest of the module works as expected according to the test plan

Note

This is a CCNA override - https://github.com/aces/CCNA/pull/6138

Looks good to me. I'll wait until @xlecours re-reviews before merging since it's changed significantly since his approval..
