Make IPD discharge complaint names and remarks editable like OPD form

FEATURE: Inline editing for discharge complaint table

PROBLEM: In IPD discharge form, complaint names and remarks were
read-only after adding. Unlike OPD consult form where you can edit
complaint names directly in the table.

SOLUTION:
1. VIEW Changes (discharge_create.php):
   - Changed complaint name and remark columns from static <td> to editable <input>
   - Added data attributes for complaint ID and original values
   - Added CSS classes: discharge-complaint-name-input, discharge-complaint-remark-input

2. JAVASCRIPT Changes:
   - Added saveComplaintField() function for AJAX updates
   - Event handlers on blur to save changes
   - Enter key support to blur and save
   - Visual feedback: green border on success, red on error
   - Auto-updates original value after successful save

3. CONTROLLER Changes (Ipd_discharge.php):
   - Added update_complaint_field() method for AJAX endpoint
   - Updates ipd_discharge_comp table (comp_report or comp_remark)
   - Returns JSON success/error response

BENEFITS:
- Same user experience as OPD consult form
- Edit complaints/remarks without page reload
- Immediate feedback on save success/failure
- Type correction and updates without removing and re-adding rows
