🔢 feat(user-edit): replace add-quota input with Semi-UI InputNumber

Summary:
• Imported InputNumber from @douyinfe/semi-ui.
• Swapped plain Input for InputNumber in “Add Quota” modal.
• Added UX tweaks: full-width styling, showClear, step = 500 000.
• Initialized addQuotaLocal to an empty string so the field starts blank.
• Adjusted state handling and kept quota calculation logic unchanged.

This improves numeric input accuracy and overall user experience without breaking existing functionality.
