[akshitrawat21]

Summary

Closes #6160

• Added eye icon toggle to Input component for all type='password' fields — covers Register page (Password & Confirm Password)
• Added show/hide toggle to Old Password, New Password, and Confirm New Password fields in Account Settings → Security section

Changes

• packages/ui/src/ui-component/input/Input.jsx — added showPassword state, IconEye/IconEyeOff as endAdornment when inputParam.type === 'password'
• packages/ui/src/views/account/index.jsx — added showOldPassword, showNewPassword, showConfirmPassword states with eye icon toggles on each OutlinedInput

Test plan

• Go to /register — verify eye icon appears on Password and Confirm Password fields
• Click eye icon — password text becomes visible
• Click again — password is masked
• Log in and go to Account Settings → Security section
• Verify eye icon on Old Password, New Password, Confirm New Password
• Verify toggle works independently for each field
• Verify no regression on other input fields (non-password types have no eye icon)

Code Review

This pull request introduces password visibility toggling functionality across the application. It updates the generic Input component and the account settings page to include eye icons that allow users to mask or unmask password fields. A review comment points out a redundant conditional check in the getInputType function that can be simplified.
