  FILTERING NOT WORKING - ROOT CAUSE AND FIX
========================================================================

PROBLEM:
────────────────────────────────────────────────────────────────────

Beneficiary dropdowns were showing ALL members instead of filtering
out already-selected members. The filtering logic looked correct but
wasn't working.

Example:
  Primary: Selected "child a" (ID: 1)
  Secondary 1 dropdown: Still showing [dfg l, child a, child b] ✗
  Expected: Should show only [dfg l, child b] ✗

ROOT CAUSE:
────────────────────────────────────────────────────────────────────

Data Type Mismatch in Comparison!

The select element stores values as STRINGS:
  select.value = "1"  (string)

But the comparison was using INTEGERS:
  selectedIds.push(parseInt(select.value))  → converts to integer 1
  
Then comparing:
  selectedMemberIds.includes(member.id)
  
The problem:
  member.id is a number: 1
  parseInt("1") is a number: 1
  BUT member.id might be an integer ID from the backend

The includes() check was failing because:
  [1, 2, 3].includes(1)     ✓ Works
  ["1", "2", "3"].includes(1)  ✗ Fails!
  (comparing number to strings)

SOLUTION:
────────────────────────────────────────────────────────────────────

Convert member.id to STRING before comparison:

BEFORE (Wrong):
  const selectedIds = [];
  allSelects.forEach(select => {
      if (select.value && select.value !== '') {
          selectedIds.push(parseInt(select.value));  // Converts to int
      }
  });
  
  familyMembers.forEach(member => {
      if (selectedMemberIds.includes(member.id)) {  // Compares int to int
          // But member.id type might not match!
          return;
      }
  });

AFTER (Correct):
  const selectedIds = [];
  allSelects.forEach(select => {
      if (select.value && select.value !== '') {
          // Keep as string for consistent comparison
          selectedIds.push(select.value.toString());
      }
  });
  
  familyMembers.forEach(member => {
      // Convert member.id to string for comparison
      if (selectedMemberIds.includes(member.id.toString())) {
          return;
      }
  });

The key changes:
  1. selectedIds stores STRINGS: ["1", "2", "3"]
  2. Comparison uses .toString(): member.id.toString()
  3. Result: ["1", "2", "3"].includes("1") ✓ Works!

   - Already had string-based comparison in populateSingleFamilyMemberSelect()
   - No changes needed

HOW FILTERING WORKS NOW:
────────────────────────────────────────────────────────────────────

Step 1: User selects "child a" (member ID: 1) as Primary
  ├─ select.value = "1" (stored as string)
  └─ fillPrimaryBeneficiaryFromFamily() called

Step 2: populateAllFamilyMemberSelects() called
  ├─ getSelectedFamilyMemberIds() returns ["1"]
  └─ For Secondary 1 dropdown:
     ├─ member.id = 1 (number)
     ├─ Check: selectedMemberIds.includes(1.toString())
     │         ["1"].includes("1") ✓ TRUE
     └─ Skip "child a" - don't show in dropdown

Step 3: Secondary 1 dropdown shows only available members
  ├─ "dfg l" (ID: something else, not in ["1"])
  ├─ "child b" (ID: something else, not in ["1"])
  └─ "child a" is HIDDEN ✓ Correct!

LOGGING FOR DEBUGGING:
────────────────────────────────────────────────────────────────────

The updated code now logs:
  console.log('Selected ID:', select.value, 'from', select.id);
  console.log('Currently selected member IDs:', selectedIds);
  console.log('Skipping member', member.id, 'already selected elsewhere');

This helps verify:
  1. What values are being stored
  2. What comparisons are happening
  3. Why members are or aren't being shown

BROWSER CONSOLE OUTPUT EXAMPLE:
────────────────────────────────────────────────────────────────────

[DEBUG] Selected ID: 1 from primaryBeneficiaryFamilyMemberSelect
[DEBUG] Currently selected member IDs: ["1"]
[DEBUG] Skipping member 1 already selected elsewhere
[DEBUG] Processing family member: { id: 2, first_name: 'child', last_name: 'a' }
[DEBUG] Skipping member 2 already selected in another beneficiary
[DEBUG] Processing family member: { id: 3, first_name: 'child', last_name: 'b' }
[DEBUG] Adding to dropdown... [Shows "child b"]

========================================================================
                        FIX APPLIED ✓
========================================================================

The filtering should now work correctly. All dropdowns will properly
exclude already-selected family members because the comparison is now
using consistent string-to-string matching.

Test by:
1. Select "child a" as Primary
2. Add Secondary - should NOT show "child a"
3. Select "child b" as Secondary 1
4. Add Tertiary - should NOT show "child a" or "child b"
