Fix: Re-initialize CKEditor after Save Discharge Advice button

ISSUE 2: After clicking 'Save Discharge Advice', CKEditor turns into plain textarea

ROOT CAUSE: initInstructionTools() was not re-initializing CKEditor after AJAX section reload
- When user clicks button with data-reload-section='section-instructions'
- Form submits via AJAX, returns updated HTML
- Section content replaced with new HTML
- initInstructionTools() called but did NOT restore CKEditor
- Fields remain as plain textareas

SOLUTION: Added CKEditor re-initialization to initInstructionTools()

Changes to discharge_create.php initInstructionTools():
1. Check if CKEDITOR is available
2. Destroy existing instances first (instruction_other, instruction_remark)
3. Re-create CKEditor for both fields with same config
4. Prevents duplicate instances and ensures editors work after reload

TESTING:
- Type in instruction_remark or instruction_other
- Click 'Save Discharge Advice'
- After reload, both fields should still be CKEditor (not textarea)
- Can continue editing with toolbar

NOTE: Issue 1 (data mixing between fields) requires separate investigation
