[FYST-1900] Make MD retirement subtraction card consistent with other states'

[arinchoi03]

Followup to #5680; noticed that all states now use the partial in the review_header but only MD does not

Link to pivotal/JIRA issue

• https://codeforamerica.atlassian.net/browse/FYST-1900

Is PM acceptance required? (delete one)

• Yes - don't merge until JIRA issue is accepted!

Reminder: merge main into this branch and get green tests before merging to main

What was done?

• Uses the same pattern as other states
  • only showing the information for subtractions for eligible_1099rs: previously we were showing this card if any 1099rs exist, and then only showing the relevant sub-elements if followup existed (which could only exist if the 1099r was qualified) which is a bit less straightforward.
• Left the disability card in the md_review b/c it needs to show if 1099Rs exist at all (at this point anyway, that's the logic); there is a followup ticket to refactor this to show if it matches the include logic on MD502R; Anyways, disability needs to be shown if 502R exists at all, so eligible_1099rs logic does not factor into showing disability-related information on the final review. I can move the whole section into the partial, if desired.
• Alternatives considered:
  • I don't like how we're putting not shared html into the shared folder, i think they should all move back into the #{stsate_code}_review folders as specific partials. However, that'll involve me moving around more copy & not sure if i want to make Aaron/September do more testing for all states 😭

note that we're changing to eligible_1099rs instead of state_file1099_rs here -- could have problems navigating back to a specific 1099R unless we have the same indices as we are using in the subtraction controllers

[arinchoi03]

in fact, we do have a problem. I used frank rollover & tried to navigate to the 2nd retirement deduction shown -- it takes me to oops page (on demo; fixed on this PR)
